A new detection method in synchronous CDMA system

摘要

Under the synchronous condition, based on the character of the receiving signal constructs and the theory of finite operator, a new decorrelating multi-user detection method is obtained. With this new method, the computation of the reverse matrix of the correlating matrix can be avoided, so it is very valid to decrease the computing complexity. Besides, the performance of this new MUD method can be convergent to the performance of the classical SISO detection.
