Abstract: In order to improve the demultiplexing performance of the mode division multiplexing system, which has Differential Group Delay (DGD), the MIMO equalizer based on Constant Modulus Algorithm (CMA) is used to demultiplex the received signal, in which the SMA is used to iterate and update the tap coefficients of the MIMO equalizer. Simulation results show that the algorithm can successfully demultiplex the received signals with crosstalk and delay and has good convergence. When the Optical Signal Noise Ratio (OSNR) in the system is greater than 18.25 dB, the Bit Error Rate (BER) of the system can reach 10-5 order magnitude, which meets the requirements of the communication system.

Key words: communication technology, optical communication, mode multiplexing, constant modulus algorithm(CMA), differential group delay(DGD)
