Abstract :
We introduce an algorithm for digital equalization of 6PolSK-QPSK signals and present a way to initialize the filter coefficients of a 2×2 adaptive time-domain equalizer in an optimum manner. The proposed algorithm has been found to perform well in both numerical simulations and transmission experiments.
