Building up low-complexity spectrally-efficient Terabit superchannels by receiver-side duobinary shaping.

Recently, an increasing interest has been put on spectrally-efficient multi-carrier superchannels for beyond 100G. Apart from orthogonal frequency-division multiplexing (OFDM) and Nyquist wavelength-division multiplexing (WDM), another low-complexity WDM approach based on transmitter-side pre-filtering and receiver-side duobinary shaping is proposed to build up multi-carrier superchannels. This...

Nonlinear Transmission Performance of Very High Spectral Efficiency WDM Comparing Nyquist Pulse Shaping and OFDM

The long distance transmission performance of Nyquist-WDM and OFDM, using PDM-QPSK at baud rate channel spacing, is investigated over uncompensated single mode fibre. Results show similar performance for both signal formats and good agreement with closed-form expressions for the nonlinear transmission performance of densely spaced coherent optical systems.

Nyquist folding digital receiver for signal interception

A new architecture, denoted as the Nyquist folding digital receiver (NYFDR), to compress the data for signal interception is presented. The NYFDR is a digital version of the Nyquist folding receiver (NYFR). Simulation results show that the NYFDR has advantages over NYFR in the detection of Nyquist zone. Moreover, the data rate and resource consumption of the NYFDR are less than those of the dig...

Equalization enhanced phase noise in Nyquist-spaced superchannel transmission systems using multi-channel digital back-propagation

Superchannel transmission spaced at the symbol rate, known as Nyquist spacing, has been demonstrated for effectively maximizing the optical communication channel capacity and spectral efficiency. However, the achievable capacity and reach of transmission systems using advanced modulation formats are affected by fibre nonlinearities and equalization enhanced phase noise (EEPN). Fibre nonlinearit...

Impairment mitigation in superchannels with digital backpropagation and MLSD.

We assess numerically the performance of single-carrier digital backpropagation (SC-DBP) and maximum-likelihood sequence detection (MLSD) for DP-QPSK and DP-16QAM superchannel transmission over dispersion uncompensated links for three different cases of spectral shaping: optical pre-filtering of RZ and NRZ spectra, and digital Nyquist filtering. We investigate the limits for carrier proximity o...
