Abstract

Code Division Multiple Access (CDMA) is one of the key technologies supporting our mobile communications today. In this paper, we analytically evaluate the performance of CDMA multi-user demodulator, when we transmit data correlated with each other. For this purpose, we utilize the replica method of statistical physics. Our analysis makes it clear that the correlation within data enables us to enhance communication efficiency in low redundancy region while the property of spread code sequence most affects the performance in high redundancy one.
