Abstract
Given an optical pulse position modulation (PPM) channel, with an average power constraint and a bandwidth constraint, this article determines the word length needed to maximize the information throughput achievable by the channel. It is shown that, to achieve the maximal capacity, the channel must be operated with a high erasure probability. This implies that coding schemes capable of compensating for a high percentage of erasures are needed for the PPM channel.
