Abstract

In this paper, we consider the structure and performance of a multistage decoding scheme for an internally bandwidth efficient convolutionally coded fiber-optic code division multiple access (CDMA) communication system. The decoder is implemented in several stages in which in each stage, the interfering users´ coded symbol decisions obtained in the previous stage is applied for computing the likelihood of the coded symbols of the desired user.
