Performance of convolutionally coded optical M-PPM systems with imperfect slot synchronization
Abstract
Performance of convolutionally coded M-ary pulse position modulation (M-PPM) systems in the presence of slot synchronization errors is evaluated for the shot-noise-limited photon-counting receiver and the avalanche photodetection (APD) receiver. Both hard and soft (delta-max) demodulation results are given, and two soft-decision metrics are investigated.
