Description

Pre-equalized information transmission methods, electronic devices and storage media Technical Field

[0001] This application relates to the field of communication technology, such as pre-equalized information transmission methods, electronic devices, and storage media. Background Technology

[0002] Point-to-multipoint time-division multiplexing passive optical networks (TDM-PON) are widely used in optical access networks due to their cost and technological advantages. With societal development, higher-speed, lower-latency access networks have become a necessary trend for future communication network development. Upgrades to Passive Optical Network (PON) systems are constantly being made. However, as system speeds increase, inter-symbol interference (ISI) caused by link dispersion and device bandwidth response limitations becomes very severe, leading to significant system performance degradation. Furthermore, in the uplink direction, processing data transmitted by different Optical Network Units (ONUs) and synchronizing different data blocks is crucial. PON currently lacks equalization algorithms, only providing a preamble field in the uplink frame for receiver clock recovery, resulting in substantial system latency. Therefore, how to correct and compensate for system impairments and reduce ISI impact through equalization techniques in digital communication systems has become an urgent problem to solve.

[0029] In the following description, the use of suffixes such as “module,” “part,” or “unit” to denote elements is solely for the purpose of illustration in this application and has no particular meaning in itself. Therefore, “module,” “part,” or “unit” may be used interchangeably.

[0030] In this embodiment of the application, by transmitting pre-equalization information during the uplink burst signal reception process in the uplink transmission direction of the passive optical network system, the equalization processing of the transmission signal of the passive optical network can be realized, avoiding the complex digital signal processing equalization of the optical line terminal receiver, and reducing system latency and power consumption.

[0031] Figure 1 is a flowchart of a pre-equalization information transmission method provided in an embodiment of this application. This embodiment of the application can be applied to the implementation of pre-equalization in a passive optical network scenario. The method can be executed by a pre-equalization information transmission device, which is generally integrated into a first node. The first node may include an optical line terminal or an optical network unit. As shown in Figure 1, the method provided in this embodiment of the application specifically includes 110-120.

[0032] 110. Determine the equalizer information based on the first information transmitted by the second node and the target equalization sequence.

[0033] The first information can be sample information used to train the equalizer information. The first information can be information that has not undergone equalization processing. The target equalization sequence can be target value information used to train the equalizer information. The target equalization sequence can be used to determine whether the equalizer information training is complete. The target equalization sequence can include synchronization header information, preamble information, and other known training sequence information. The equalizer information can be relevant information of the equalizer used for equalization processing. The equalizer information can include the weight parameters of the equalizer. The aforementioned equalizer can include linear equalizers, nonlinear equalizers, adaptive equalizers, and fractional interval equalizers, etc.

[0034] In this embodiment of the application, the second node can transmit the first information and the target equalization sequence to the first node. The first node can use the first information and the target equalization sequence to determine the equalizer information. This determination process can include determining it through a neural network model, or training the equalizer to generate it through the first information and the target equalizer information.

[0035] 120. The registration and activation process based on optical network units transmits equalizer information to the second node.

[0036] The registration and activation process of an optical network unit (ONU) can be an initialization process that enables the ONU to correctly access the optical line terminal (OLT). This process, as shown in Figure 2, can include physical connection and power-on in state O1, automatic discovery and initial information exchange in state O2, ranging and signal parameter adjustment in state O3, detailed information exchange and authentication / authorization in state O4, and configuration and service startup in state O5. In some embodiments, the generation process of uplink / downlink frames in the ONU registration and activation process can be as shown in Figures 3 and 4. Service data is encapsulated into XGEM frames, a series of XGEM frames are further encapsulated into FS frames, then PSBd is added and FEC checksum is inserted for scrambling, and when bit interleaving is required, the final transmitted physical frame is generated. The downlink physical frame has a period of 125 microseconds, and each uplink frame originates from the same ONU.

[0037] In this embodiment of the application, the equalization information obtained by the first node can be transmitted to the second node during the registration and activation process of the optical network unit, so that the second node can configure its own equalizer according to the equalization information, so as to use the equalizer to perform equalization processing on the communication signal during the passive optical network communication process.

[0038] In this embodiment, by acquiring the first information and the target equalization sequence transmitted by the second node, and determining the equalizer information based on the first information and the target equalization sequence, the equalizer information is transmitted to the second node during the registration and activation process of the optical network unit, thereby realizing the transmission of equalizer information. This facilitates equalization processing based on equalizer information within the passive optical network transmission system, which can improve the signal transmission quality of the passive optical network and enhance the user experience.

[0039] Based on the above application embodiments, the target equalization sequence includes at least one of the following: synchronization header information, preamble information, and other known training sequence information.

[0040] In this embodiment, when the first node is an ONU, the target equalization sequence used to determine the equalization information may include synchronization header information. This synchronization header information can be used by the first node to determine the equalizer information. The first node is an OLT, and the target equalization sequence may be preamble information. Furthermore, the target equalization sequence may also be other known training sequence information, which can be used to train the equalizer to obtain the equalizer information.

[0041] Figure 5 is a flowchart of another pre-equalization information transmission method provided in the embodiment of this application. The embodiment of this application describes the process of generating equalizer information. Referring to Figure 5, the method provided in the embodiment of this application specifically includes the following steps 210-230.

[0042] 210. Input the first information into the equalizer and adjust the weight parameters of the equalizer.

[0043] Equalizers can be used to handle time-varying and frequency-selective fading in passive optical network systems, improving signal transmission quality. Equalizers can include linear equalizers, nonlinear equalizers, adaptive equalizers, and fractional interval equalizers, etc.

[0044] In this embodiment of the application, the first information can be input into the equalizer, and the equalizer processes the first information with the current weight parameters to obtain the output information.

[0045] 220. Determine that the error value between the output information of the equalizer and the target equalization sequence meets the preset conditions, and use the weight parameters as the equalizer information.

[0046] The preset conditions can be used to determine the completion of equalizer training. The preset conditions can include the minimum error value between the output information and the target equalization sequence.

[0047] The equalizer's output is compared with the target equalization sequence. If the error between the two meets a preset condition, such as being less than a first threshold, the equalizer training is considered complete, and the weight parameters of the equalizer at this point can be used as the equalizer information. If the error between the equalizer's output and the target equalization sequence does not meet the preset condition, the process of adjusting the weight parameters can be returned to step 210.

[0048] In one exemplary embodiment, Figure 6 illustrates a linear equalizer that may include a training phase and a tracking phase. During the training phase, a high-speed training sequence is input to the linear equalizer. The high-speed training sequence is weighted and summed with the weights of the linear equalizer. Error feedback is used to adjust the weight values ​​of the linear equalizer to minimize the error between the output sequence and the training sequence, thus completing the training phase of the linear equalizer. Then, during the tracking phase, the linear equalizer directly processes the transmitted signal using the equalized decision symbols.

[0049] 230. The registration and activation process based on optical network units transmits equalizer information to the second node.

[0050] Figure 7 is a flowchart of another pre-equalization information transmission method provided by an embodiment of this application. This embodiment is a specific embodiment based on the above embodiment, and describes the case where the first node includes an optical network unit. Referring to Figure 7, the method provided by this embodiment specifically includes the following steps 310-320.

[0051] 310. Determine the equalizer information based on the first information transmitted by the second node and the target equalization sequence.

[0052] 320. Equalizer information is transmitted after the optical network unit sequence number field of the physical layer operation, management and maintenance messages.

[0053] In this embodiment of the application, during the activation and registration process of the optical network unit, the optical network unit acting as the first node can transmit the equalizer information to the second node after sending the optical network unit serial number field of the physical layer operation, management and maintenance message to the second node, so that the second node can configure its own equalizer through the equalizer information.

[0054] In other embodiments, the method further includes transmitting equalizer information after the registration field of the physical layer operation, management, and maintenance message.

[0055] In this embodiment of the application, the optical network unit, which is the first node, can also transmit to the second node after the registration field of the physical layer operation, management and maintenance message.

[0056] Figure 8 is a flowchart of another pre-equalization information transmission method provided by an embodiment of this application. This embodiment is a specific embodiment based on the above embodiment, and describes the case where the first node includes an optical line terminal. Referring to Figure 7, the method provided by this embodiment specifically includes the following steps 410-420.

[0057] 410. Determine the equalizer information based on the first information transmitted by the second node and the target equalization sequence.

[0058] 420. Equalizer information is transmitted after the optical network unit identifier field of the physical layer operation, management and maintenance messages.

[0059] During the activation and registration process of an optical network unit, the optical line terminal, acting as the first node, can transmit the equalizer information to the second node after sending the allocated optical network unit identifier field for physical layer operation, management, and maintenance messages to the second node. This allows the second node to configure its own equalizer using the equalizer information.

[0060] In other embodiments, the method further includes transmitting equalizer information after the ranging time field of the physical layer operation, management and maintenance message.

[0061] In this embodiment of the application, during the activation and registration process of the optical network unit, the optical line terminal, as the first node, can also transmit equalizer information to the second node after the ranging time field of the physical layer operation, management and maintenance message.

[0062] Based on the above application embodiments, the equalizer information is carried in the outer information frame of the registration and activation process.

[0063] In this embodiment, equalizer information can be implemented through uplink or downlink frames within the registration and activation process. Specifically, the uplink and / or downlink frames can be the outermost information frames of the registration and activation process, such as the outermost physical frames shown in Figures 2 and 3.

[0064] Figure 9 is a flowchart of another pre-equalization information transmission method provided in the embodiment of this application. The embodiment of this application can be applied to the pre-equalization situation in the passive optical network scenario. The method can be executed by the pre-equalization information transmission device, which is generally integrated into the second node. The second node may include an optical line terminal or an optical network unit. As shown in Figure 9, the method provided in the embodiment of this application specifically includes the following steps 510-520.

[0065] 510. Transmit the first information and the target equilibrium sequence to the first node.

[0066] In this embodiment of the application, the second node can transmit the first information and the target equalization sequence to the first node. The first node can use the first information and the target equalization sequence to determine the equalizer information. This determination process can include determining it through a neural network model, or training the equalizer to generate it using the first information and the target equalizer information.

[0067] 520. The registration and activation process based on optical network units receives equalizer information transmitted by the first node, wherein the equalizer information is determined based on the first signal and the target equalization sequence.

[0068] The equalization information transmitted by the first node can be received during the registration and activation process of the optical network unit. The second node can configure its own equalizer according to the equalization information so that the equalizer can be used to equalize the communication signal during the passive optical network communication process.

[0069] Based on the above-mentioned application embodiments, the equalizer information is determined based on the first signal and the target equalization sequence, including: inputting the first information into the equalizer of the first node and adjusting the weight parameters of the equalizer of the first node; determining that the error value between the output information of the equalizer of the first node and the target equalization sequence meets a preset condition, and using the weight parameters as equalizer information.

[0070] Based on the above-described embodiments, the equalizer includes at least one of a linear equalizer, a nonlinear equalizer, an adaptive equalizer, and a fractional interval equalizer.

[0071] Figure 10 is a flowchart of another pre-equalization information transmission method provided in the embodiment of this application. When the first node of the embodiment of this application includes an optical network unit, the process of receiving equalization information is described. Referring to Figure 10, the method provided in the embodiment of this application specifically includes the following steps 610-620.

[0072] 610. Transmit the first information and the target equilibrium sequence to the first node.

[0073] 620. The equalizer information transmitted after receiving the optical network unit sequence number field of physical layer operation, management and maintenance messages.

[0074] In this embodiment of the application, during the activation and registration process of the optical network unit, the optical network unit acting as the first node can transmit equalizer information to the second node after sending the optical network unit serial number field of the physical layer operation, management and maintenance message to the second node. The second node receives the equalizer information after the optical network unit serial number field of the physical layer operation, management and maintenance message.

[0075] In other embodiments, the equalizer information is also included after receiving the registration field of physical layer operation, management and maintenance messages.

[0076] The second node can transmit equalizer information after the registration field of the physical layer operation, management, and maintenance message.

[0077] Figure 11 is a flowchart of another pre-equalization information transmission method provided in the embodiment of this application. When the first node of the embodiment of this application includes an optical line terminal, the process of receiving equalization information is described. Referring to Figure 11, the method provided in the embodiment of this application specifically includes the following steps 710-720.

[0078] 710. Transmit the first information and the target equilibrium sequence to the first node.

[0079] 720. The equalizer information transmitted after receiving the allocation optical network unit identifier field of physical layer operation, management and maintenance messages.

[0080] The first node can transmit equalizer information after the allocation optical network unit identifier field in the physical layer operation, management, and maintenance messages, and the second node can transmit equalizer information after the allocation optical network unit identifier field in the physical layer operation, management, and maintenance messages.

[0081] In some embodiments, the application also includes equalizer information transmitted after receiving the ranging time field of physical layer operation, management and maintenance messages.

[0082] Based on the above application embodiments, the equalizer information is carried in the outer information frame of the registration and activation process.

[0083] In an exemplary implementation, referring to Figure 12, the ONU's linear equalizer enters the first training phase. For an ONU to be activated, it needs to complete the online process through a registration and activation procedure. After the ONU is powered on, the receiver's linear filter is turned on, entering the synchronization phase. The downstream synchronization state machine is initialized, using the PSBd synchronization header as the target sequence after equalization, and the received synchronization header sequence as the input sequence of the linear filter. The convergence of the tap weight values ​​is completed through an adaptive equalization algorithm. Interoperation is performed between the PSBd synchronization header and the adaptively equalized code block. If the calculated coefficients are greater than a certain threshold value, it is determined that the first phase of synchronization with the downstream PHY frame has been completed. The equalizer coefficients at this time are recorded and saved, and the ONU enters the O2 and O3 states. The OLT sends an SN request message, which is then parsed by the ONU, which sends an uplink Serial_Number_ONU PLOAM message. At this point, the equalizer coefficients saved in the previous step are added to the ONU's transmitter. Since the Serial_Number_ONU PLOAM field has been fully used, a new uplink Physical Layer Operation, Administration and Maintenance (PLOAM) message can be sent afterward. See the table below for an example of the content of the new PLOAM message.

[0084] Table 1 Downlink Equalizer Messages

[0085]

[0086] In this embodiment, referring to Figure 13, the ONU continues the normal registration and activation process to complete the ONU online function. Although the uplink and downlink use different wavelengths to transmit data, since the physical links are the same, the corresponding filter parameters can be trained indirectly. After going online, the second stage, the tracking stage, begins. During downlink transmission, the OLT sends the trained linear filter parameters to the corresponding ONU via a BWmap message. The ONU can then activate the pre-equalizer in the frame structure of the physical adaptive sublayer by sending user data uplink. In this embodiment, the receiving side does not need to directly output the linear filter to complete the uplink reception, but it can still retain its linear filter because the pre-equalization algorithm added by the ONU can reduce the complexity of the OLT filter and the convergence time of the algorithm. Referring to Figure 14, the BWmap message is carried in the outermost layer of the uplink frame.

[0087] In another exemplary implementation, referring to Figure 15, during the first training phase, for the ONU to be activated, after the synchronization process with the downstream PHY frame is completed, the equalizer coefficients are recorded and saved, and the normal activation process enters the O4 state. The OLT sends a ranging request message, which the ONU parses and then sends an uplink Registration PLOAM message. At this time, the saved equalizer data is added to the ONU's transmitter. Since the Registration PLOAM field has been fully used, a new uplink PLOAM message can be added after it. An example of the content of the newly added PLOAM message is shown in Table 2 below.

[0088] Table 2 Downlink Equalizer Messages

[0089]

[0090] In other embodiments, referring to Figure 16, during the first training phase, the linear filter of the OLT is activated. For the ONU to be activated, the convergence of pre-equalization parameters can be directly achieved using the information transmitted from the uplink during the O2 and O3 phases of the activation process. The code block transmitted from the ONU uplink contains a specific preamble field, which is known to the OLT. This field is used as the target sequence after equalization for the linear filter, and the sequence to be equalized received from the uplink is used as the input sequence for the linear filter. The convergence of the tap weight values ​​is achieved through an adaptive equalization algorithm.

[0091] Referring to Figure 17, when the ONU comes online normally, upon entering O2, O3, and the OLT sending the SN request message, the ONU parses it and sends the Serial_Number_ONU PLOAM message upstream. After the OLT successfully parses the message, it completes the parameter convergence of the linear equalizer and saves the equalizer data. If it is necessary to send the corresponding ONU linear filter parameters at this time, since the Assign_ONU-ID PLOAM field has been fully used, a new PLOAM message can be added after it. See Table 3 below for an example of the content of the new PLOAM message.

[0092] Table 3 Uplink Equalizer Messages

[0093]

[0094] Once the ONU comes online, it enters the second tracking phase. During downlink transmission, the OLT sends the trained linear filter parameters to the corresponding ONU via a BWmap message. During uplink transmission, user data is sent, and pre-equalizer parameters can be added to the frame structure of the physical adaptive sublayer. In some other embodiments, see Figure 18, for ONUs to be activated, the pre-equalizer parameters can be converged directly using the uplink-sent preamble field during the O4 phase of the activation process. When the ONU comes online normally and enters O4, the OLT sends a ranging request message. After the ONU parses the message, it sends a Registration PLOAM message uplink. After successful parsing, the OLT completes the equalizer parameter convergence. At this point, the equalizer data is saved and added to the Ranging_Time PLOAM information subsequently sent by the OLT, which is then sent downlink to the corresponding ONU, completing the subsequent registration process. See Table 4 below for details of the PLOAM message.
