Pilot Distributions for Joint-Channel Carrier-Phase Estimation in Multichannel Optical Communications
Arni F. Alfredsson, Erik Agrell, Magnus Karlsson +1
Joint-channel carrier-phase estimation can improve the performance of multichannel optical communication systems. In the case of pilot-aided estimation, the pilots are distributed…
Optimization of Transmitter-Side Signal Rotations in the Presence of Laser Phase Noise
Arni F. Alfredsson, Erik Agrell, Magnus Karlsson +1
The effects of transmitter-side multidimensional signal rotations on the performance of multichannel optical transmission are studied in the presence of laser phase noise. In parti…
Pilot-Aided Joint-Channel Carrier-Phase Estimation in Space-Division Multiplexed Multicore Fiber Transmission
Arni F. Alfredsson, Erik Agrell, Henk Wymeersch +4
The performance of pilot-aided joint-channel carrier-phase estimation (CPE) in space-division multiplexed multicore fiber (MCF) transmission with correlated phase noise is studied.…
Iterative Detection and Phase-Noise Compensation for Coded Multichannel Optical Transmission
Arni F. Alfredsson, Erik Agrell, Henk Wymeersch
The problem of phase-noise compensation for correlated phase noise in coded multichannel optical transmission is investigated. To that end, a simple multichannel phase-noise model…
