This paper studies a variable rate optical Orthogonal Frequency Division Multiplexing Passive Optical Network (OFDM-PON) real-time access system model, using the signal processing method of oversampling. The basic principle of the model is that the access system uses different oversampling rates according to the allocated bandwidth to different Optical Network Units (ONUs), ensuring that the entire system can utilize the existing hardware conditions to maximum effect. The proposed system uses Xilinx V5 FPGA to generate real-time OFDM signals. MATLAB software is used to recover the signals and calculate the bit error rate (BER). The simulation results are presented and analyzed to verify the performance of the system. |
