An improved blind space-time multiuser detection in multipath CDMA channels
多径CDMA信道下的一种改进的盲空时多用户检测

An improved LMS blind space-time multiuser detection method based on the Rosen's gradient projection to realize in multipath CDMA channels is presented. Comparison with the original method, the proposed method has advantages in complexity and requirement of the system. However, the results of simulation comparison illustrate that the detection performance of the proposed multiuser space-time processing method do not deteriorate, and prove that this method has advantage over the original method in the competition of market.
