Abstract :
We numerically simulate the influence of mode coupling and modal delay on the transmitted signal. Then we carry out adaptive signal processing with MIMO equalizers based on recursive least squares constant modulus algorithm (RLSCMA). The simulation results show that the distorted signals are restored efficiently with fast convergence speed.
