MIMO Equalization to Mitigate Crosstalk Degradation in a Dual-Channel OAM Multiplexed System

In this paper, we demonstrate crosstalk degradation mitigation using minimum mean-square error (MMSE) algorithm combined constant modulus algorithm (CMA) in a dual-channel OAM multiplexed system. For OFDM-16QAM signals with up to −3dB crosstalk is recovered.
