Abstract

In this paper, a comparison of some coding schemes of rate 0:4 over a Rayleigh fading multipath channel in CDMA systems are given. The rst coding scheme employs outer Reed-Solomon codes (RS) concatenated with inner NASA convolutional code proposed for CODIT system [1]. The second scheme employs a punctured convolutional code of rate 2 5 , and the third scheme is a punctured turbo code of the same rate. The performance of the three schemes are analysed, and the single-cell CDMA capacity is computed.
