Coherent detection: n-ary PPM versus PCM

Cryan, R.A., Unwin, Rodney T., Massarella, Alistair J. and Sibley, Martin J.N. (1991) Coherent detection: n-ary PPM versus PCM. Proceedings of SPIE, 1372. pp. 64-71. ISSN 0277-786X
Abstract

In this paper we present computer results at 1. 5zm comparing coherent n-ary PPM with coherent PCM. We show that for a given fibre bandwidth there is an optimum word size and this occurs when the equivocations attributed to the error sources in n-ary PPM are equal. We conclude that for moderate to high fibre bandwidths homodyne n-ary PPM should achieve an improvement in sensitivity of typically 5 dB over homodyne PSK PCM
