Abstract

We proposed an adaptive equalisation scheme that has both fast polarisation tracking capability and transceiver IQ impairment tolerance based on partial freezing of the multiple-input multiple-output structure. Experimental results showed superior equalisation performance of the scheme to previous ones under polarisation fluctuations exceeding 11 Mrad/s.
