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
