Weighted Decision Enhanced Phase-Retrieval Receiver with Adaptive Intensity Transformation

We report a weighted decision enhanced phase-retrieval receiver with adaptive intensity transformation (WD_AIT_PR). When 56 GBaud 16QAM signals are transmitted over the 80km SSMF, the WD_AIT_PR receiver is verified to outperform other newly-reported counterparts, in terms of convergence speed, steady BER performance, and imperfections tolerance.
