摘要：
The performance of LDPC-coded CDMA system was analyzed using the replica method of statistical mechanics, in the infinite codelength and large system limits. Thus, most existing studies of such systems consider the case of a finite number of users. In particular, the analysis gives the information-theoretic and decoding thresholds of the optimum joint detection/decoding scheme.
