In this paper, we show numerically and experimentally that expectation maximization (EM)
algorithm is a powerful tool in combating system impairments such as fibre nonlinearities …

Coherent optical satellite links enable high‐throughput communication and high accuracy
ranging to and between satellites. Due to the ever‐increasing demand for throughput …

Timing recovery is critical for synchronizing the clocks at the transmitting and receiving ends
of a digital coherent communication system. The core of timing recovery is to determine …

Since the timing error detectors sensitivity (TEDS) of the timing recovery algorithm is close to
zero under the singularity condition of azimuth θ about±π/4 and differential group delay …

We propose a novel timing recovery algorithm (TRA) for Nyquist digital multi-band optical
coherent systems. The proposed TRA employs two complementary metrics to cover all …

As mudanças nos padrões de tráfego na internet forçam a constante evolução das redes
ópticas, que, por serem sistemas com grande capacidade e se estenderam por milhares de …

Sistemas de comunicações ópticas coerentes digitais permitem a utilização de formatos de
modulação que carregam informação através de fase, amplitude e polarização do sinal …

We present an analysis of clock recovery algorithms in both polarization division
multiplexing systems and mode division multiplexing systems. The impact of inter …
