Description

Technical Field

[0001] This invention belongs to the field of next-generation information network industry technology, and in particular relates to a method and system for network repeater spectrum reuse and fusion processing. Background Technology

[0002] Currently, with the continuous advancement of broadband internet construction and the ongoing convergence of the three networks in my country, more and more users are starting to use IP-based broadband services. The era of converged broadband communications has arrived, making many IP-based multimedia services possible, such as broadband cinemas, online TV stations, video conferencing, distance education, telemedicine, network video surveillance, and online live streaming systems.

[0003] Repeater technology, as a network supplementation technique, is already widely used in existing fixed networks. Based on current equipment and network configurations, spectrum reuse during repeater operation is not currently considered. Therefore, with the increasing number of private network applications and rapid emergency response needs, the development of repeater control methods that can quickly adapt to various environments or dynamic changes will effectively address the growing demands of these applications, including those in private networks and emergency situations.

[0004] Based on the above analysis, the problems and shortcomings of the existing technology are as follows:

[0005] 1) Research and application of spectrum reuse technology: In order to improve spectrum utilization, repeater solutions based on spectrum reuse technology can be researched and developed. For example, multiple access technologies (such as OFDMA) and wavelength division multiplexing technologies (such as DWDM) can be used to enable multiple users to share communication resources in the same frequency band, thereby improving spectrum utilization efficiency.

[0006] 2) Intelligent network management and scheduling: By introducing more intelligent network management and scheduling strategies, dynamic allocation and optimization of spectrum resources can be achieved. For example, machine learning and artificial intelligence technologies can be used to monitor and predict network status in real time, and dynamically adjust spectrum resource allocation strategies according to demand.

[0007] 3) Network layer optimization: In terms of network architecture, a multi-layered network design can be considered to achieve different levels of service quality. For example, the network can be divided into a core layer, an aggregation layer, and an access layer to provide differentiated services for user needs at different levels.

[0008] 4) Introduction of cooperative communication technology: By introducing cooperative communication technology, resource sharing and cooperation among multiple network nodes can be achieved, improving the overall network performance. For example, cooperative relay technology (such as CoMP) can be used to achieve cooperative transmission between multiple repeaters, reducing interference and improving signal quality.

[0009] 5) Convergence of Heterogeneous Networks: In practical applications, the convergence of repeater networks with other wireless communication networks (such as cellular networks, Wi-Fi networks, etc.) can be considered to achieve more flexible and efficient network resource sharing and management. For example, multi-access edge computing (MEC) technology can be used to deploy multiple access technologies on edge network nodes, enabling seamless switching and interoperability between multiple networks.

[0010] 6) Construction of a rapid emergency communication network: To address rapid emergency response needs, a rapid deployment and flexible scheduling emergency repeater network solution can be researched and developed. For example, UAVs carrying repeater equipment can be used to achieve rapid deployment and dynamic adjustment of network coverage.

[0011] In conclusion, by researching and applying new technologies and network management strategies, we can solve the problems and shortcomings of existing repeater technologies, such as spectrum reuse, thereby meeting the growing needs of private network applications and rapid emergency response. Summary of the Invention

[0012] To address the problems existing in the prior art, this invention provides a method and system for network repeater spectrum reuse and fusion processing.

[0013] This invention is implemented as follows: a network repeater spectrum reuse and fusion processing method and system. The network repeater spectrum reuse and fusion processing method includes: extracting the required signal spectrum according to the needs of the subsequent signal through windowing and other processing; modulating the local information to the corresponding position according to the unused spectrum information obtained by the subsequent signal; and receiving the signal of the previous node while the subsequent node repeats the signal of the previous node.

[0014] Furthermore, the network repeater spectrum reuse and fusion processing method can achieve complementarity with the repeater spectrum by selectively modulating and transmitting the local spectrum position, thereby achieving full-spectrum transmission and maximizing spectrum utilization; the local modulation signal of the node can be modulated to the corresponding spectrum either by spectrum shifting or by modulation control processing.

[0015] Another object of the present invention is to provide a network repeater spectrum multiplexing and fusion processing system, the network repeater spectrum multiplexing and fusion processing system comprising:

[0016] The chain-like repeater spectrum multiplexing processing module is used to perform spectrum repeating and multiplexing processing on each node under chain network conditions.

[0017] The ring repeater spectrum multiplexing processing module is used to perform spectrum repeating and multiplexing processing on each node under ring network conditions;

[0018] The star-shaped repeater spectrum multiplexing processing module is used to perform spectrum repeating and multiplexing processing on each node in a star network configuration.

[0019] Based on the above network configurations, the hybrid network configurations composed of the above network configurations can also be directly reproduced and reused.

[0020] Furthermore, in the chain-like repeater processing module, when the priority intermediate node is reused:

[0021] (1) Node 1 borrowed 1 / 4 of the resources from node 0 in the right direction and 1 / 12 of the resources from node 4 in the left direction. Therefore, the amount of data that node 1 can send changed from 1 to 4 / 3 before and after reuse.

[0022] (2) Node 2 borrowed 2 / 4 of the resources from node 0 and 1 / 3 of the resources from node 1 in the right direction, and borrowed 2 / 4 of the resources from node 4 and 1 / 3 of the resources from node 3 in the left direction. Therefore, the amount of data that node 2 can send changed from 1 to 8 / 3 before and after reuse.

[0023] (3) Node 3 borrowed 1 / 4 of the resources from node 4 in the left direction and 1 / 12 of the resources from node 0 in the right direction. Therefore, the amount of data that node 3 can send changed from 1 to 4 / 3 before and after reuse.

[0024] (4) Since there are no resources available for the sending nodes in the sending direction, the amount of data transmitted by nodes 0 and 4 remains unchanged;

[0025] Under these conditions, the total amount of interactive data information in the system changed from 5 before and after reuse to (1+4 / 3+8 / 3+4 / 3+1)=22 / 3, and its transmission efficiency increased by 22 / 3 / 5-1=46.7%.

[0026] Furthermore, in the chain repeater processing module, when the priority two-end nodes perform spectrum reuse, the total amount of interactive data information in the system changes from the original 5 to (4 / 3+4 / 3+7 / 3+4 / 3+4 / 3)=23 / 3 before and after reuse, and its transmission efficiency is improved by 23 / 3 / 5-1=53.33%.

[0027] Furthermore, in the chain repeater processing module, when all nodes in the network reuse data with the same amount of information transmitted, the total amount of interactive data information in the system changes from the original 5 to 5 / 3*5=25 / 3 before and after reuse, and its transmission efficiency is improved by 25 / 3 / 5-1=66.67%.

[0028] Furthermore, in the ring repeater processing module, when all nodes transmit the same amount of information, the change in the amount of information that each node can send before and after multiplexing is as follows:

[0029] (1) When node 0 sends a signal in a clockwise direction, it uses 1 / 2 of its own spectrum resources, borrows 1 / 2 of node 2's resources, and borrows 1 / 3 of node 1's resources; when it sends a signal in a counterclockwise direction, it uses 1 / 2 of its own spectrum resources, borrows 1 / 2 of node 3's resources, and borrows 1 / 3 of node 4's resources; therefore, after multiplexing, the amount of signal data sent by node 0 changes from 1 to 8 / 3.

[0030] (2) When node 1 sends a signal in a clockwise direction, it uses half of its own spectrum resources, borrows half of node 3's resources, and borrows one-third of node 2's resources; when it sends a signal in a counterclockwise direction, it uses half of its own spectrum resources, borrows half of node 4's resources, and borrows one-third of node 0's resources; therefore, after multiplexing, the amount of signal data sent by node 1 changes from 1 to 8 / 3.

[0031] (3) Nodes 2 to 4 undergo the same multiplexing process as described above, and the amount of signal data transmitted after multiplexing changes from 1 to 8 / 3.

[0032] Under ring conditions, full spectrum reuse can be achieved, and the total amount of interactive data in the system changes from 5 to (4 / 3+4 / 3)*5=40 / 3, and its transmission efficiency is improved by 22 / 3 / 5-1=166.7%.

[0033] Furthermore, in the star-shaped repeater processing module, when all nodes transmit the same amount of information and the central node provides directional coverage, full spectrum reuse can be achieved under star conditions. The reuse method is to centralize the processing with the central point 6 as the node, and process the remaining nodes in a ring. Thus, it can be seen that the total amount of interactive data information in the system changes from 6 to 6*(5*1 / 2)=15, and its transmission efficiency is improved by 15 / 6-1=150%.

[0034] In addition to the multiplexing and allocation mechanism described above, signals can also be processed by coordinated direct amplification and coordinated multiplexing according to the transmission needs of each node in the network, so that the network transmission needs can be met through coordinated direct amplification and multiplexing.

[0035] Another object of the present invention is to provide a computer device, the computer device including a memory and a processor, the memory storing a computer program, which, when executed by the processor, causes the processor to perform the steps of the network repeater spectrum multiplexing fusion processing method.

[0036] Another objective of this invention is to provide an information data processing terminal for implementing the aforementioned network repeater spectrum reuse and fusion processing system.

[0037] Based on the above technical solutions and the technical problems solved, the advantages and positive effects of the technical solution to be protected by this invention are as follows:

[0038] First, based on the characteristics of repeater and combined with partial repeater processing, this invention proposes a partial repeater spectrum reuse and fusion mechanism. It utilizes the echo cancellation capability of the repeater system to perform partial repeater processing on demand, and reuses the spectrum on the basis of partial repeater, thereby improving the spectrum utilization rate.

[0039] 1) Improve spectrum utilization: By implementing spectrum reuse during repeater operation, this method can effectively improve the utilization of spectrum resources. This helps alleviate the problem of spectrum resource scarcity and supports the needs of more users and application scenarios.

[0040] 2) Increased communication capacity: Enabling multiple users to share communication resources within the same frequency band can significantly increase communication capacity. This helps improve network performance and meet the ever-growing demand for data transmission.

[0041] 3) Flexible spectrum allocation strategy: By dynamically acquiring unused spectrum information, this method can implement a flexible spectrum allocation strategy to adapt to changes in different scenarios and needs. This helps improve the network's adaptability and intelligence.

[0042] 4) Reduce interference and improve signal quality: Through signal fusion and demodulation separation techniques, this method can effectively reduce interference between signals and improve signal quality. This helps to reduce communication errors and improve communication reliability.

[0043] 5) Expanding application scenarios: This method is applicable to various network repeater scenarios, including fixed networks, mobile networks, and private networks. This helps to expand the application of network repeater technology in different fields and meet a wider range of needs.

[0044] 6) Reduce network construction and operation costs: By improving spectrum utilization and communication capacity, this method can reduce network construction and operation costs. This helps alleviate the burden on operators and improve the economic efficiency of network services.

[0045] In summary, the above-mentioned network repeater spectrum reuse and fusion processing method has significant advantages and positive effects, which helps to promote the development and application of network repeater technology and meet the growing communication needs.

[0046] Second, considering the full network connectivity, this invention adopts a repeater spectrum reuse method, which can improve the network spectrum efficiency by 66.67% under chain network conditions. Assuming that the amount of information transmitted by each node is the same, the spectrum efficiency of ring and star networks can be improved by 166.7% and 150% respectively, which greatly improves the spectrum efficiency of the system.

[0047] Third, as supplementary evidence of the inventive step of the claims of this invention, it is also reflected in the following important aspects:

[0048] (1) The expected benefits and commercial value of the technical solution of the present invention after transformation are as follows: Through the technical solution of the present invention, the spectrum utilization rate can be greatly improved without increasing the system cost, and the transmission capacity of the system can be increased; to a certain extent, the equipment investment is reduced, the equipment installation workload is reduced and the requirements for the equipment installation location are reduced, thus reducing the overall system cost.

[0049] (2) The technical solution of the present invention fills the technical gap in the industry at home and abroad: The technical solution of the present invention has not been studied in the current network, thus filling the technical gap in this technical direction;

[0050] (3) Does the technical solution of the present invention solve the technical problem that people have been eager to solve but have never been able to solve successfully? The technical solution of the present invention addresses the problem of increasingly scarce spectrum resources by proposing an effective method and system for improving spectrum utilization. Through this spectrum reuse method, by adopting a multi-point collaborative reuse processing method in different networks, the entire network can meet the needs of various static or dynamic network forms, which can improve the transmission efficiency of fixed networks and greatly improve the transmission efficiency of dynamic networks.

Detailed Implementation

[0058] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0059] To address the problems existing in the prior art, the present invention provides a method and system for network repeater spectrum reuse and fusion processing. The present invention will be described in detail below with reference to the accompanying drawings.

[0060] Detailed signal and data processing procedures of the network repeater spectrum reuse and fusion processing method provided in this embodiment of the invention:

[0061] 1) Signal Spectrum Extraction: In network repeater operation, the subsequent signal needs to be processed first to extract the required signal spectrum. This can be achieved through windowing methods (such as Hanning window, Hamming window, etc.). Windowing can reduce signal spectrum leakage, improve spectral resolution, and thus obtain the signal's spectral information more accurately.

[0062] 2) Acquisition of unused spectrum information: During local signal modulation, it is necessary to obtain unused spectrum information according to the requirements of subsequent signals. This can be achieved by analyzing the extracted signal spectrum to find idle spectrum resources and provide available spectrum locations for local information modulation.

[0063] 3) Local information modulation: After acquiring unused spectrum information, the local information is modulated to the appropriate location. This can be achieved by selecting a suitable modulation scheme (e.g., QPSK, QAM, etc.) to adapt to different channel conditions and data rate requirements.

[0064] 4) Signal fusion: After local information modulation is completed, the fused signal is sent to the downstream node. This means that the downstream node can receive the signal from the previous node in addition to receiving the signal from the previous node.

[0065] 5) Signal Demodulation and Separation: After receiving the fused signal, the downstream node needs to perform signal demodulation and separation. First, the received signal is demodulated to restore the original signal. Then, a signal separation algorithm (such as blind source separation) is used to separate the signal from the previous node's signal for subsequent processing.

[0066] 6) Signal processing and transmission: Perform necessary signal processing (such as filtering, decoding, etc.) on the separated signals, and then transmit the processed signals to the next level network node or end user.

[0067] Through the above signal and data processing, this method realizes spectrum reuse and fusion processing in network repeaters, effectively improving spectrum utilization and meeting the needs of different users and application scenarios.

[0068] The following are examples of six network repeater spectrum reuse and fusion processing methods:

[0069] Example 1: Spectrum multiplexing and fusion processing in a chain repeater network

[0070] In a chain repeater network, the nodes are connected sequentially to form a chain topology. In this case, the chain repeater processing module is responsible for processing the chain repeater spectrum, realizing spectrum reuse and fusion. This implementation is suitable for one-to-many communication scenarios, such as point-to-multipoint wireless communication systems.

[0071] Example 2: Spectrum multiplexing and fusion processing in a ring repeater network

[0072] In a ring repeater network, the nodes are connected end-to-end, forming a ring topology. The ring repeater processing module is responsible for processing the ring repeater spectrum, enabling spectrum reuse and fusion. This implementation is suitable for communication networks with ring topologies, such as ring fiber optic access networks.

[0073] Example 3: Spectrum multiplexing and fusion processing in a star repeater network

[0074] In a star repeater network, the central node is connected to other nodes, forming a star topology. The star repeater processing module is responsible for processing the repeater spectrum in the star network configuration, enabling spectrum reuse and fusion. This implementation is suitable for star-topology communication networks, such as satellite communication systems and wireless local area networks.

[0075] Example 4: Spectrum reuse fusion processing in multi-hop repeater networks

[0076] In multi-hop repeater networks, signals are transmitted through multiple relay nodes. In this embodiment, each node can employ chain, ring, or star repeater processing modules for spectrum reuse and fusion processing, depending on its location and role. This embodiment is suitable for spectrum resource management in multi-hop networks, such as wireless sensor networks and mobile ad hoc networks.

[0077] Example 5: Spectrum reuse fusion processing of dynamic spectrum allocation strategy

[0078] This embodiment achieves spectrum reuse and convergence in network repeaters through a dynamic spectrum allocation strategy. In this method, each node dynamically adjusts spectrum resource allocation based on network status and service requirements to adapt to changes in different scenarios and needs. This embodiment is applicable to fields such as dynamic spectrum access and cognitive wireless networks.

[0079] Example 6: Spectrum multiplexing and fusion processing with adaptive modulation

[0080] In this embodiment, each node adaptively selects a suitable modulation scheme (e.g., QPSK, QAM, etc.) for local information modulation based on channel conditions and data rate requirements. This embodiment can effectively improve network performance and adapt to changes in different channel conditions. It is suitable for adaptive modulation and coding systems, such as 4G, 5G, and future 6G communication networks.

[0081] Through the above six embodiments, this invention demonstrates the wide applicability and flexibility of the network repeater spectrum reuse fusion processing method in different application scenarios.

[0082] To enable those skilled in the art to fully understand how the present invention is specifically implemented, this section provides an explanatory description of the embodiments that expand upon the technical solutions of the claims.

[0083] 1. Repeater spectrum reuse mechanism

[0084] In multi-node network communication, since a node needs to receive signals (or signal spectra) from the preceding node, and the next node needs signals (or signal spectra), a repeater system can employ partial repeating, only processing the signals needed by the downstream nodes. In this case, a portion of the signal space at the transmitting end remains unused. To reuse the spectrum, selective modulation of the local spectrum space is used, complementing the repeater portion and achieving full-spectrum transmission, thus maximizing spectrum utilization. For example... Figure 1 The diagram shows a block diagram of repeater spectrum multiplexing processing. The specific operation is as follows: First, the system extracts the required signal spectrum according to the needs of the subsequent signal through windowing and other processing. The local modulated signal obtains unused spectrum information according to the needs of the subsequent signal and modulates the local information to the corresponding position. The subsequent node receives the signal from the previous node while simultaneously receiving the local signal sent by that node.

[0085] The modulation of the node's local modulation signal to the corresponding spectrum can be achieved either through spectrum shifting or through modulation control processing.

[0086] 2. Reuse processing mechanism

[0087] 2.1 Chain-like

[0088] The following analysis uses a chain-like direct placement as an example. Figure 2 As shown, assuming that the amount of data sent by any node reaches the same amount of data to any other node in the network, the changes in the amount of data that each node can send before and after multiplexing are as follows:

[0089] 1) Node 1 borrowed 1 / 4 of the resources from node 0 to the right and 1 / 12 of the resources from node 4 to the left. Therefore, the amount of data that node 1 can send changed from 1 to 4 / 3 before and after reuse.

[0090] 2) Node 2 borrowed 2 / 4 of the resources from node 0 and 1 / 3 of the resources from node 1 in the right direction, and borrowed 2 / 4 of the resources from node 4 and 1 / 3 of the resources from node 3 in the left direction. Therefore, the amount of data that node 2 can send changed from 1 to 8 / 3 before and after multiplexing.

[0091] 3) Node 3 borrowed 1 / 4 of the resources from node 4 to the left and 1 / 12 of the resources from node 0 to the right. Therefore, the amount of data that node 3 can send changed from 1 to 4 / 3 before and after reuse.

[0092] 4) Since there are no resources available for the sending nodes in the sending direction, the amount of data transmitted by nodes 0 and 4 remains unchanged;

[0093] Therefore, under these conditions, the total amount of interactive data information in the system changes from (1+1+1+1+1)=5 before and after reuse to (1+4 / 3+8 / 3+4 / 3+1)=22 / 3, and its transmission efficiency is improved by 22 / 3 / 5-1=46.7%.

[0094] like Figure 3 As shown, under chain conditions, when the priority two-end nodes perform spectrum reuse, the total amount of interactive data information of the system changes from (1+1+1+1+1)=5 to (4 / 3+4 / 3+7 / 3+4 / 3+4 / 3)=23 / 3 before and after reuse, and its transmission efficiency is improved by 23 / 3 / 5-1=53.33%.

[0095] like Figure 4 As shown, under chain-like conditions, when all nodes in the network reuse data with the same amount of information transmitted, the total amount of interactive data information in the system changes from (1+1+1+1+1)5 to 5 / 3*5=25 / 3 before and after reuse, and its transmission efficiency is increased by 25 / 3 / 5-1=66.67%.

[0096] 2.2 Circular

[0097] The following analysis uses a ring-shaped upright arrangement as an example. Figure 5As shown, assuming that when any node sends data, the amount of data it sends to any other node in the network is the same, the changes in the amount of information that each node can send before and after multiplexing are as follows:

[0098] As can be seen from the above,

[0099] 1) When node 0 transmits a signal in a clockwise direction, it uses half of its own spectrum resources, borrows half of node 2's resources, and borrows one-third of node 1's resources; when transmitting a signal in a counterclockwise direction, it uses half of its own spectrum resources, borrows half of node 3's resources, and borrows one-third of node 4's resources; therefore, after multiplexing, the amount of signal data transmitted by node 0 changes from 1 to 8 / 3.

[0100] 2) When Node 1 transmits signals in a clockwise direction, it uses half of its own spectrum resources, borrows half of Node 3's resources, and borrows one-third of Node 2's resources; when transmitting signals in a counter-clockwise direction, it uses half of its own spectrum resources, borrows half of Node 4's resources, and borrows one-third of Node 0's resources; therefore, after multiplexing, the amount of signal data transmitted by Node 1 changes from 1 to 8 / 3.

[0101] 3) Nodes 2 to 4 undergo the same multiplexing process as described above, and the amount of transmitted signal data changes from 1 to 8 / 3 after multiplexing;

[0102] Therefore, under ring conditions, full spectrum reuse can be achieved, and the total amount of interactive data of the system changes from 5 to (4 / 3+4 / 3)*5=40 / 3, and its transmission efficiency is improved by 22 / 3 / 5-1=166.7%.

[0103] 2.3 Star-shaped

[0104] The following analysis uses a star network configuration with repeater as an example. Assuming that when any node sends data, the amount of data it sends to any other node in the network is the same, the changes in the amount of information each node can send before and after multiplexing are as follows: Figure 6 As shown.

[0105] Under star topology, full spectrum reuse can be achieved. The reuse method is to centralize the processing with the center point 6 as the node, and process the remaining nodes in a ring. Thus, the total amount of interactive data information of the system changes from 6 to 6*(5*1 / 2)=15, and its transmission efficiency is improved by 15 / 6-1=150%.

[0106] To demonstrate the inventiveness and technical value of the technical solution of this invention, this section provides specific product or related technology application examples of the technical solution claimed.

[0107] An application embodiment of the present invention provides a computer device, which includes a memory and a processor. The memory stores a computer program, and when the computer program is executed by the processor, the processor performs the steps of a network repeater spectrum reuse fusion processing method.

[0108] An application embodiment of the present invention provides a computer-readable storage medium storing a computer program, which, when executed by a processor, causes the processor to perform the steps of a network repeater spectrum multiplexing fusion processing method.

[0109] The network repeater spectrum multiplexing and fusion processing system provided in this embodiment of the invention can be understood as a communication system that can process repeater spectrum under different topologies to improve network transmission efficiency.

[0110] Specifically, this system comprises three modules: a chain-like repeater processing module, a ring-like repeater processing module, and a star-like repeater processing module. These modules can correspond to different types of network structures to achieve optimal spectrum reuse and repeater processing under different conditions.

[0111] 1. Chain-like direct-play processing module

[0112] The chain repeater processing module is used to process the repeater spectrum in a chain network structure. In a chain network, each node is only connected to its adjacent nodes, so time-division multiplexing (TDM) can be used for spectrum reuse. Specifically, each node transmits data in different time periods to avoid spectrum resource conflicts. The repeaters in the chain repeater processing module can perform signal processing, selection, filtering, multiplexing, fusion, and amplification on the transmitted signal to improve signal quality, transmission distance, and spectral efficiency. Furthermore, the module can also utilize the power difference between interval nodes to reuse the time and frequency resources of interval nodes, further improving spectrum utilization.

[0113] 2. Circular direct-view processing module

[0114] The ring repeater processing module is used to process the repeater spectrum in a ring network structure. In a ring network, each node is connected to its neighboring nodes, so frequency division multiplexing (FDM) can be used for spectrum reuse. Specifically, different nodes transmit data on different frequency bands to avoid spectrum resource conflicts. The repeaters in the ring repeater processing module can perform signal processing, selection, filtering, multiplexing, fusion, and amplification on the transmitted signal to improve signal quality, transmission distance, and spectral efficiency. Furthermore, the module can utilize the power difference between interval nodes to reuse the time and frequency resources of interval nodes, further improving spectrum utilization.

[0115] 3. Star-shaped direct-drive processing module

[0116] The star-shaped repeater processing module is used to process the repeater spectrum in a star network structure. In a star network, the central node is connected to each peripheral node, so time-division multiplexing (TDM) or frequency-division multiplexing (FDM) can be used for spectrum multiplexing. Specifically, the central node distributes data to the peripheral nodes, and then each node transmits data at a different time or frequency band to avoid spectrum resource conflicts. The repeater in the star-shaped repeater processing module can perform signal processing, selection, filtering, multiplexing, fusion, and amplification on the transmitted signal to improve signal quality, transmission distance, and spectral efficiency. Furthermore, the module can also utilize the power difference between interval nodes to multiplex the time and frequency resources of the interval nodes, further improving spectrum utilization.

[0117] In summary, this network repeater spectrum reuse and fusion processing system can select the optimal spectrum reuse and repeater processing methods according to different network topologies to improve network transmission efficiency and signal quality.

[0118] An application embodiment of the present invention provides an information data processing terminal, which is used to implement the network repeater spectrum reuse fusion processing system.

[0119] An application embodiment of the present invention provides a communication device for implementing the network repeater spectrum multiplexing fusion processing system.

[0120] The embodiments of the present invention have achieved some positive results during the research and development or use process, and have indeed great advantages compared with the prior art. The following content describes them in conjunction with the data, charts and other information of the experimental process.

[0121] See Figures 2-4 The reuse method and the spectrum enhancement efficiency obtained from the above theoretical calculations; Figures 2-4 The 1 in the text indicates that the full spectrum is used.
