چکیده
The performance of polarization multiplexed, quadrature phase shift keying (PM QPSK) and polarization multiplexed 16-ary quadrature amplitude modulation (PM 16-QAM) is considered with an emphasis on the signal processing algorithms that compensate transmission impairments and implement key receiver functions.

OSNR monitoring for QPSK and 16-QAM systems in presence of fiber nonlinearities for digital coherent receivers.
OSNR monitoring is indispensable for coherent systems to ensure robust, reliable network operation and potentially enable impairment-aware routing for future dynamic optical networks. In a long-haul transmission link with chromatic dispersion (CD) and fiber nonlinearity, it is difficult to distinguish between amplifier noise and fiber nonlinearity induced distortions from received signal distri...

Recently, coherent-detection (CoD) polarization multiplexed (PM) transmission has attracted considerable interest, specifically as a possible solution for next-generation systems transmitting 100 Gb/s per channel and beyond. In this context, enabled by progress in ultra-fast digital signal processing (DSP) electronics, both multilevel phase/amplitude modulated formats (such as QAM) and orthogon...
متن کاملA Novel Optical Carrier Phase Estimation Technique Based on Viterbi-Viterbi and QPSK Partitioning for 16-QAM
We propose a novel carrier phase estimator based on two-stage Viterbi-Viterbi and QPSK partitioning for 16-QAM. Simulation shows that the proposed algorithm is highly tolerant to laser linewidth with a reduced cycle slip probability.

Coherent-detection (CoD) permits to fully exploit the four-dimensional (4D) signal space consisting of the in-phase and quadrature components of the two fiber polarizations. A well-known and successful format exploiting such 4D space is Polarization-multiplexed QPSK (PM-QPSK). Recently, new signal constellations specifically designed and optimized in 4D space have been proposed, among which pol...
