The drive for higher performance in optical fiber systems has renewed interest in coherent
detection. We review detection methods, including noncoherent, differentially coherent, and …

Recent progress in coherent optical communication, a field revived by advances in digital
signal processing (DSP), is reviewed. DSP-based phase and polarization management …

We report on an optical intradyne receiver experiment with frequency estimation. Frequency
estimation allows, if performed prior to block phase estimation or other phase recovery …

We analytically studied the block length effect (BLE) of decision-aided maximum likelihood
(DA ML) carrier phase estimation in coherent optical phase-modulated systems. The results …

Soft-decision-based forward error correction (FEC) and its practical implementation for 100
Gb/s transport systems are discussed. In applying soft-decision FEC to a digital coherent …
