Effect of Imperfect Phase Reference on Soft Demodulation and Decoding of DE-QPSK in Optical Transmission Systems [PDF]

, 2014
The performance of non-iterative soft demodulation for coded modulation schemes based on the serial concatenation of a low-density parity check (LDPC) code and differentially encoded (DE) quadrature phase shift keying (QPSK) modulation in presence of phase noise is considered.

Coded octal PSK system performance disturbed by imperfect recovered phase reference

Electronics and Communications in Japan (Part I: Communications), 1985
AbstractThere have been various investigations on the PSK modulation technique which is encoded by a convolutional code. For the bandwidth constrained transmission, such as satellite communications, it is important to hold a high information transmission rate.

Performance of trellis coded M-PSK and neural network equivalent systems over partial response-fading channels with imperfect phase reference

Proceedings of ICUPC - 5th International Conference on Universal Personal Communications, 2002
For the first time in the literature, a partial response-fading channel is introduced. The new channel model acts like partial response signalling (PRS) having Rician probability density function. Analytical upper bounds of the trellis coded M-PSK structures are derived using Chernoff bounding technique, combined with the modified generating functional
