Enhanced Carrier Phase Recovery Using Dual Pilot Tones in Faster-than-Nyquist Optical Transmission Systems

Photonics
Compared with high spectrum efficiency faster-than-Nyquist (FTN) backbone network, an enhanced carrier phase recovery based on dual pilot tones is more sensitive to capital cost in FTN metropolitan areas as well as inter-datacenter optical networks.

Multi-criteria Performance Analysis of Faster Than Nyquist Signaling

, 2018
International audienceIn this paper we propose a multi-criteria comparison of faster than Nyquist (FTN) against Nyquist signaling. To conduct this study we consider uncoded links and maximum likelihood receivers, we fix both the spectral efficiency (SE ...

Faster-than-Nyquist modulation based on short finite pulses [PDF]

, 2008
We investigate faster-than-Nyquist modulation based on short finite pulses over the AWGN channel. We consider several pulse shapes and compare their information rates for several system setups. We compare the effect of increasing the alphabet size versus

Low-complexity FTN receivers based on frequency domain iterative decision feedback equalization

Tongxin xuebao, 2017
Faster-than-Nyquist (FTN) signaling can improve the system effectiveness without reducing the system reliability,but the fierce inter-symbol interference (ISI) introduced by it may cause that the complexity of the optimal receiver is intolerable.An ...
