The variance of the phase error using the parallel DA ML is analytically examined. The bit-error-rate performance is also analytically investigated in different M-ary phase-shift keying (PSK) systems. The results show that parallel DA ML can outperform block Mth-power in binary PSK format, while suffering performance penalty originating from parallelism and pipelining in high-order PSK formats. © 2009 IEEE.||Source Title:||IEEE Photonics Technology Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/56985||ISSN:||10411135||DOI:||10.1109/LPT.2009.2028580|
