Paper Abstract

A modified phase recovery algorithm with overlap controlled adaptively used for squared 16-QAM is proposed, which is based on the 4th-power algorithm and relieve the problem of block-size-choosing. By using this modified algorithm, 1.8MHz linewidth tolerance for 25G Baud 16-QAM is improved on traditional 4th-power algorithm.
