摘要：
This paper is concerned with the performance of a residue number system (RNS) bared direct-sequence CDMA system over bursty communication channels. Concatenated codes employing redundant RNS as inner codes and convolution codes as outer codes are adopted to improve the system performance. An efficient interleaving method is designed to enhance the system performance. A simplified channel model represented by a three-state Markov process is presented for bursty communication channels. The proposed system is extensively simulated for different channel parameters for both multipath environment and for bursty channels. The results show that the performance of the system is better than similar systems when the SNR is sufficiently high.
