Description

Technical Field

[0001] The present invention belongs to the field of communication technology, and in particular relates to an anti-interference communication method and system under denial conditions. Background Art

[0002] In certain scenarios, the entire environment is subject to a large amount of active interference. The interferer can successfully disrupt current communications by applying high-power interference to the target frequency band, causing a sharp drop in the signal-to-noise ratio of the current communication band. When interference exists in the physical frequency band, an effective anti-interference solution is to adjust the current communication band to a band that is not affected by interference or is less affected by interference. Because each communication standard operates on a specific frequency band, the above process essentially adjusts the current communication standard from the one that is being interfered with to the one that is not.

[0003] Spectrum sensing technology in cognitive radio can be used to monitor the status of each frequency band. In cognitive radio systems, unlicensed devices use spectrum sensing to distinguish valid signals from randomly fluctuating noise within a specific frequency band. Cognitive radio can also use spectrum sensing to detect interference and locate available spectrum resources. Because each communication standard operates on a fixed frequency band, determining available spectrum resources is equivalent to determining the available standards. After obtaining information about the currently available spectrum, the most appropriate communication standard must be selected for switching. In a multi-standard wireless communication network, a terminal can simultaneously establish connections with multiple access networks operating in different frequency bands, transmitting information through multiple transmission paths based on different communication standards. However, due to the inherent performance limitations of the communication standards and the varying effects of external interference on transmission performance across different spectrums, the communication standards supported by a terminal can exhibit significant differences in performance metrics such as transmission rate, bit error rate, transmit power, and average latency. Therefore, when certain channels are severely interfered with, the terminal needs to comprehensively consider the impact of the system performance parameters, adaptively switch the communication system, and use the channel with the globally optimal communication system for communication, thereby reducing the impact of interference and improving the network's reliability, transmission rate, and anti-interference performance in a denied environment.

[0004] The decisive metric for vertical handoff algorithms based on received signal strength is received signal strength (RSS). When the received signal strength of the original standard falls below that of the new standard, the mobile device switches to the new network. Because received signal strength is affected by external factors and can become unstable, this can lead to frequent handoffs between standards. Frequent handoffs increase handoff latency, severely impacting communication quality and resulting in significant resource waste. Therefore, researchers have proposed optimization schemes based on this. One such scheme combines received signal strength with other parameters, incorporating a delay time. When the received signal strength of the new standard exceeds that of the original standard, the handoff is temporarily suspended. After the delay time expires, if the received signal strength of the new standard is still greater than that of the original standard, the handoff is resumed. This optimization method reduces unnecessary handoffs.

[0005] During vertical handover, given the complex network environment, it's no longer enough to consider only received signal strength alone; instead, multiple standard attributes must be considered for decision-making. These attributes include signal-to-noise ratio, transmission rate, bit error rate, channel capacity, handover delay, and jitter.

[0006] Traditional handover algorithms rely on vertical handover based on received signal strength (RSS). This algorithm uses RSS as its decisive metric. When the received signal strength of the currently used standard is detected to be lower than that of an alternative standard, the mobile device automatically switches to the new network with a stronger signal. However, RSS is a performance metric susceptible to external factors. Factors such as building obstruction, changing weather conditions, and multipath can all cause erratic fluctuations in RSS. This instability makes RSS-based handover algorithms prone to misjudgment, ultimately leading to frequent switching between standards. Frequent handovers increase handover latency, severely impact communication quality, and result in significant resource waste. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to address the deficiencies in the above-mentioned prior art and provide an anti-interference communication method and system under denied conditions, which can adaptively switch communication modes and use the channel where the globally optimal communication mode is located for communication, thereby reducing the impact of interference and improving the reliability, transmission rate and anti-interference performance of the network in a denied environment, and is used to solve the technical problem of multi-mode communication switching in a denied environment.

[0042] Compared with the prior art, the present invention has at least the following beneficial effects:

[0043] A method for anti-interference communication under denial conditions sets the transmit power strength of each communication standard and dynamically adjusts the communication environment. This method ensures adaptive selection of the optimal communication standard in different application scenarios, maintaining optimal communication performance in various environments. This method's advantage lies in its ability to adapt the communication standard to actual conditions when the transmitter and receiver are in relative motion, improving communication flexibility and stability.

[0044] Furthermore, by setting a judgment threshold to filter out uninterrupted communication modes and grouping these noise-free modes into a candidate set, the system's interference recognition capabilities can be effectively improved. This step ensures that when faced with strong interference, the system can quickly filter out the interfered modes, thereby reducing the signal transmission failure rate and improving communication quality.

[0045] Furthermore, switching decision criteria include transmission rate, signal-to-noise ratio, bit error rate, and received signal strength. These comprehensive considerations ensure that the selected standard not only offers a high transmission rate but also maintains stable communication performance in interference environments. Using these decision-making metrics, the system optimizes channel switching strategies, improving interference resistance and transmission efficiency.

[0046] Furthermore, a weighted average of the parameters of each communication standard is used for selection, ensuring that each communication standard switching decision is based on the global optimal decision. This method weights the characteristics of different communication standards to ensure that the selected standard has better overall performance than other candidate standards, thereby improving the system's overall anti-interference capabilities.

[0047] Furthermore, the setting of benefit-based parameters and cost-based parameters ensures that when faced with different network conditions, the system can intelligently distinguish which standards have higher benefits and which standards have higher costs, thereby helping the system make better switching decisions and achieve the effect of saving resources and improving communication efficiency.

[0048] It can be understood that the beneficial effects of the second aspect mentioned above can be found in the relevant description of the first aspect mentioned above, and will not be repeated here.

[0049] In summary, the present invention can achieve adaptive and intelligent communication mode switching under denial conditions, ensuring that the system can always operate at optimal performance in complex interference environments, thereby maximizing communication efficiency and security.

[0064] The present invention provides an anti-interference communication method under denial conditions. On the basis of a simple weighted method, a time delay threshold is added to set a trigger condition. The trigger switching condition is the interference noise situation on each standard. When the interference noise occurs, the optimal standard is selected through a switching algorithm to perform standard switching. The time delay threshold is set to improve the reliability and stability of the switching and avoid waste of resources. On the basis of a multi-standard communication standard switching algorithm, a simulation implementation of an anti-interference system in a denial environment is completed. By jointly optimizing the signal-to-noise ratio, bit error rate, transmission rate and received signal strength under different communication standards, the multi-standard communication system is switched to work under the communication standard with the best performance in real time, thereby improving the transmission efficiency and safety performance of the multi-standard communication system.

[0065] See also Figure 1 The present invention provides an anti-interference communication method under a denial condition, comprising the following steps:

[0066] S1. Set the transmit power strength for each communication mode and select the appropriate communication environment based on the actual application scenario. Dynamically adjust the power based on whether the transmitter and receiver are moving relative to each other. Different communication scenarios will correspond to different wireless transmission losses.

[0067] Set the transmission power intensity of each communication system on the scene setting page , select the scene and whether the transmitter and receiver are relatively mobile. Different scenes will correspond to different wireless transmission losses. Therefore, the setting of step S1 determines the subsequent standard switching indicators.

[0068] S2. In all communication modes, accurately determine whether interference noise exists based on the interference noise detection results;

[0069] By setting the threshold, the undisturbed systems are screened out, and these noise-free systems are combined into a candidate system set. ; The severely interfered standards are eliminated, the number of standards entering the candidate standard set is reduced, and the computational complexity of subsequent steps is reduced.

[0070] In the decision-making process of system switching, the interference noise of each system is fully considered. When the interference noise of a certain system exceeds a certain threshold, it is regarded as a condition to trigger switching. In all available links, it is judged whether there is interference noise, and the system without interference is selected to form a set. as follows:

[0071] (1)

[0072] in, It is The noise of the network, Indicates the set noise threshold.

[0073] S3. Calculate the set based on the data Switching decision indicators for Chinese standards;

[0074] The switching decision indicators are selected as transmission rate, signal-to-noise ratio, bit error rate and received signal strength.

[0075] The bit error rate comes from the real-time detection of the interference identification module.

[0076] The received signal strength is calculated by the difference between the base station's transmitted signal power and the wireless transmission loss.

[0077] Received signal strength reflects the actual received strength of the base station's transmitted signal after accounting for wireless transmission losses and is a crucial factor in ensuring communication stability. This paper uses the Okumura-Hata model to calculate radio signal propagation path loss. Urban areas consider the impact of buildings, roads, and man-made structures on the signal, as well as multipath effects and terrain undulations. Suburban areas prioritize the impact of natural terrain on signal transmission. For hilly terrain, a correction factor can be applied based on the suburban loss. Hilly terrain parameters can be expressed as "terrain undulation" height. This refers to the difference in height between the 90th and 10th percentiles of terrain undulation within a 10km radius from the receiving point to the transmitting point. References indicate that the correction value increases with increasing terrain parameters. The relative height of hills is generally considered to be no more than 200m. In this paper, this is assumed to be 200m, and the corresponding correction value is -16dB. Therefore, when calculating hilly terrain in this project, the transmission loss for open suburban areas is first calculated, and the hilly terrain correction factor is then incorporated.

[0078] The standard formula for median path loss in urban areas is:

[0079] (4)

[0080] For large cities:

[0081] (5)

[0082] (6)

[0083] For small and medium-sized cities:

[0084] (7)

[0085] The path loss correction for suburban areas is:

[0086] (8)

[0087] The path loss correction for hilly terrain is:

[0088] (9)

[0089] in, is the operating frequency, is the effective antenna height of the base station transmitter, is the effective antenna height of the mobile station receiver, is the distance between the transmitting and receiving antennas, is the correction factor for the effective antenna height of the mobile station receiver, is the correction factor for hilly areas.

[0090] Therefore, the received signal strength is expressed as:

[0091] (10)

[0092] The signal-to-noise ratio is calculated as the ratio between the transmit power and the noise power, as follows:

[0093] (2)

[0094] The transmission rate is calculated using Shannon's formula.

[0095] (3)

[0096] In order to more accurately calculate the wireless transmission loss, the present invention adopts the classic Okumura-Hata model.

[0097] S4. Normalize each parameter to eliminate the dimensional differences between different parameters;

[0098] The normalized parameter value is , after weighted summation, the weighted average value of the parameters of each communication standard is obtained; step S4 comprehensively considers the impact of multiple key factors on standard switching, thereby improving the rationality and accuracy of the switching decision.

[0099] In order to ensure the fairness and effectiveness of each performance parameter in the decision-making process, a normalization method is used to convert each parameter value into a dimensionless value under a unified scale.

[0100] Wireless network performance parameters are divided into benefit-based parameters and cost-based parameters. Benefit-based parameters, such as received signal strength, should be as large as possible, while cost-based parameters, such as bit error rate, should be as small as possible. Equations (8) and (9) are used to normalize benefit-based and cost-based parameters, respectively, and the parameter values ​​can be normalized to the range [0, 1].

Indicates the normalized value. For benefit-type parameters, if the actual network parameter is less than The minimum value of the parameter, i.e. ,but is 0; if greater than The maximum value of the parameter, ,but For cost parameters, if the actual network parameters are less than The minimum value of the parameter, i.e. ,but is 1; if greater than The maximum value of the parameter. ,but is 0.

[0104] The normalized value obtained Perform weighted summation according to the following formula to obtain the weighted average value of the parameters of each communication standard.

[0107] S5. Perform a secondary selection based on the weighted average value, find the format with the highest weighted average value, and switch to it;

[0108] Step S5 ensures the accuracy and efficiency of the mode switching and improves the overall performance of the wireless communication system.

[0109] To avoid frequent handoffs and resource waste caused by the ping-pong effect, the present invention sets a time delay threshold. Only when the handoff clock exceeds this threshold will vertical handoff to the standard with the highest weighted average be executed. Otherwise, the delay is accumulated and the above process is repeated. This design ensures the reliability and stability of handoff decisions.

[0110] S6. Display the entire system switching process through dynamic graphics.

[0111] During the process of switching the standard, the interference situation and parameter indicators are displayed at the same time; this helps users to understand the real-time situation of the standard switching more intuitively, making it easier to monitor and adjust.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0140] This paper proposes a multi-mode communication switching strategy based on an improved simple weighted method, and demonstrates its efficient switching capability and anti-interference performance in complex electromagnetic environments through experimental data: by introducing a time hysteresis threshold, the number of switching times was reduced by 40%, thereby reducing the impact of the ping-pong effect. This shows that the strategy can significantly improve system stability; at 0.05 milliseconds and 0.075 milliseconds, the algorithm successfully identified interference and executed switching, ensuring that more than 90% of the network transmission rate remained stable, a 15% improvement over traditional methods; in simulations involving scenarios with multiple modes such as shortwave, ultra-shortwave, LTE, and satellite communications, the switching success rate reached 98%, indicating that the algorithm can achieve stable and efficient communication mode switching in a variety of complex environments.

[0141] Experimental data shows that this invention effectively enhances anti-interference capabilities by switching between multiple communication modes, maintaining high transmission rates and stability in high-interference environments. The system intelligently selects the optimal communication mode by comprehensively considering multiple indicators, such as signal-to-noise ratio, transmission rate, and bit error rate. This reduces unnecessary switching and significantly improves resource utilization and communication quality.

[0142] See also Figure 2 , which is a multi-standard switching simulation diagram of the present invention.

[0143] The present invention can simulate switching between multiple standards, meeting the requirement of switching at least three standards. These standards include shortwave, ultra-shortwave, mobile communications, and satellite communications. It also demonstrates how the transmission rate of the selected standard changes as the switching process progresses. Due to the inevitable delay between detection and standard switching, the transmission rate initially decreases when encountering interference. However, as the standard switching is completed, the transmission rate gradually recovers, showing a trend of first decreasing and then increasing.

[0144] See also Figure 3 , which is a diagram illustrating the switching process of the present invention.

[0145] The present invention presents the entire system switching process through dynamic graphics. Figure 2 This image shows the complete switching process. The interference situation and the changes in various parameters of the currently selected standard are also displayed during the switching process. The bit error rate, transmission rate, and signal-to-noise ratio change as the interference situation changes.

[0146] In summary, the present invention provides an anti-interference communication method and system under denial conditions, which enhances anti-interference capabilities and provides reliable communication services in strong interference environments. It also comprehensively considers multiple indicators such as transmission rate, signal-to-noise ratio, bit error rate, and received signal strength to intelligently select the optimal communication mode, reducing unnecessary switching and resource waste, thereby improving communication efficiency and stability. This method can achieve efficient mode switching and optimize resource allocation in complex environments, and is particularly suitable for scenarios such as military communications and emergency communications that require high levels of anti-interference and stable transmission.
