The present invention relates to a method for detecting CDMA signal in code division multiple access wireless communication system. It can make receiver of base station have no need of using training series to can calculate multi-user propagation channel parameters. Said blind recognition method includes the following steps: firstly, using subspace information of data matrix to estimate characteristic wave form of single user; on the basis of estimated characteristic wave form, using obtained sampled data and using receiver algorithm to implement decision and restoration of transmitted CDMA signal. Said invention can be used in synchronous and asynchronous CDMA systems, and can be used for raising received signal quality by combining with additional diversity technique on the multi-antenna packet testing base station and for solving synchronization and frequency fading affect in the moving system. |
