摘要：

We describe a system with multi-input multi-output (MIMO) transmission over 7-core few-mode fiber (FMF) by incorporating polarization division multiplexing and mode division multiplexing. Three optical modes with x and y polarizations were used for 42 x 42 MIMO transmission over 7-core FMF. We simulate the optical MIMO transmission at 20 Gbps with quadrature phase-shift keying signals. By using the adaptive recursive least squares constant modulus algorithm (RLSCMA) at the receiver side, transmission data is successfully recovered by mitigating the effects of modal delay and mode coupling of received signals. The simulation results show that adaptive RLSCMA can improve the system performance of optical MIMO transmission systems.
