Abstract
In this analysis, performance evaluation of orthogonal convolutional coded pulse position modulation (PPM) in a typical binary‐asymmetric optical channel is presented. Then, the system performance is compared to that of the Reed‐Solomon coded PPM model, where high background noise affects the channel behavior. Using an avalanche photodetector for detection, threshold decision technique is used. This treatment for the PPM orthogonal convolutional coding is more comprehensive than that described in reference 1.Keywords
