Abstract

In this article, the effect of processing gain has been analyzed on optical coded IDMA at minimum loss. Processing gain is efficient parameter for direct–sequence spread spectrum communication on performance of optical IDMA system. IDMA is a recent multiple access technique through which multiple access interference (MAI) and inter symbol interference (ISI) can be minimized in the communication network. The convolutional codes are also used in this communication system for better error correction with variable processing gain and using random and tree inter-leaver in optical coded IDMA technique. In this article low rate convolutional codes are used, provides significant improvement in probability of error (Pe). By increasing the processing gain the performance of system will be enhanced. In this article effect of spreading i.e. processing gain variation is observed for random and tree inter-leaver for different number of users.
