Mitigation of thermal gradient-induced crosstalk using CMA-based multi-channel equalisation.

(a) Received power and channel crosstalk of OAM  = +1 and  = +3 over 28 seconds and (b) instantaneous BER of OAM  = +1 and  = +3 over 28 seconds with and without CMA equalisation under thermal gradient-induced turbulence when both channels are transmitted. (c) Measured BER curves of OAM channel  = +1 and  = +3 with and without CMA equalisation. Ch.: channel. Eq.: equalization.
