Abstract
Performance of two coding systems is analyzed in this study for a noisy optical channel with M(= 2^m)-ary orthogonal signaling and random-gain photomultiplier detection. The considered coding systems are the Reed-Solomon (RS) coding with error-only correction decoding and the interleaved binary convolutional system with soft decision Viterbi decoding. The required average number of received signal photons per information bit, Np for a desired bit error rate of 10^-6 is found for a set of commonly used parameters and with a high background noise level. We find that the interleaved binary convolutional coding system is preferable to the RS coding system in performance-complexity tradeoffs.
