WebOct 27, 2024 · Chromatic dispersion equalization (CDE) in coherent optical communication systems is extremely critical for subsequent digital signal processing (such as frequency offset estimation and carrier phase recovery). Various methods mentioned in the published literature are not satisfactory when the signal bandwidth is limited. This paper proposes a … WebIn 2005, the demonstration of digital carrier-phase estimation in coherent receivers re-stimulated a widespread interest in coherent optical communi-cations [2]. The reason is that the digital coherent receiver enables us to employ a variety of spectrally-efficient modulation formats such as M-ary
