A family of Nyquist pulses for coherent optical communications.
A new family of Nyquist pulses for coherent optical single carrier systems is introduced and is shown to increase the nonlinearity tolerance of dual-polarization (DP)-QPSK and DP-16-QAM systems. Numerical investigations for a single-channel 28 Gbaud DP-16-QAM long-haul system without optical dispersion compensation indicate that the proposed pulse can increase the reach distance by 26% and 19%,...
متن کاملReal-time coherent detection of phase modulated ultrashort pulses after time-to-space conversion and spatial demultiplexing.
Phase modulated sub-picosecond pulses are converted by a time-to-space processor to quasi-monochromatic spatial beams that are spatially demultiplexed and coherently detected in real-time. The time-to-space processor, based on sum-frequency generation (SFG), serves as a serial-to-parallel converter, reducing the temporal bandwidth of the ultrashort pulse to match the bandwidth of optoelectronic...
متن کاملTransmission and full-band coherent detection of polarization-multiplexed all-optical Nyquist signals generated by Sinc-shaped Nyquist pulses
All optical method is considered as a promising technique for high symbol rate Nyquist signal generation, which has attracted a lot of research interests for high spectral-efficiency and high-capacity optical communication system. In this paper, we extend our previous work and report the fully experimental demonstration of polarization-division multiplexed (PDM) all-optical Nyquist signal gener...
متن کاملDesign of Nyquist and Near-Nyquist Pulses with Spectral Constraints
Two design procedures, one based on switched pulse shapes, and the other based on alternating projections in the time and frequency domain, are used to obtain interference and jitter-free or reduced interference and jitter (near-Nyquist) pulse-shaping filters. The latter method, that incorporates both frequencyand timedomain constraints into the linear filter design procedure, allows common pul...
متن کاملDenoising Of TDM Signal Using Novel Time Domain and Transform Domain Multirate Adaptive Algorithms
The Gaussian noise is obvious in most of the communication channels. The impulsive noise tends to Gaussian form as the time slot extends over a significant period. In this paper a channel with Gaussian noise is considered. A TDM signal passed through this kind of channel was applied to denoising. The denoising was implemented in time as well as transform domain. The adaptive algorithms like LMS...
