▷

Demonstration of a novel optical transmitter for high-speed differential phase-shift-keying/ inverse-return-to-zero (dpsk/inv-rz) orthogonally modulated signalsAbstract—We propose and experimentally demonstrate a simple and novel optical transmitter for superimposing 10-Gb/s differential phase-shift-keying signals on a 10-Gb/s inverse-return-to-zero signal....

MDP différentielle

DPSK

électronique et électrotechnique - iate.europa.eu

Ce procédé consiste à démoduler des signaux optiques MDP différentielle (DPSK) tels que des signaux DPSK binaire (DBDPSK) et des signaux DPSK en quadrature (DQPSK) communément utilisés.

A filter-based method of demodulating differentially encoded phase shift keyed (DPSK) optical signals, such as commonly used binary-DPSK (DBDPSK) and quadrature DPSK (DQPSK) signals, that can achieve optimal receiver sensitivity is described.

On the bit error rate of lightwave systems with optical amplifiers... We compute the exact probability of error and the optimal threshold and compare them with those predicted by Gaussian approximations for ASK, FSK or DPSK modulations, both for ideal photodetectors and for the case where shot noise is significant....
