摘要 该文在多径CDMA信道下基于Rosen梯度投影实现的最小均方盲空时多用户检测方法的基础上提出了一种改进的方法,该方法与原有的方法相比,运算量有所降低、对系统的要求降低,但通过仿真结果比较表明,该方法的检测性能与原有的方法大致相当,因而更加具有竞争力。 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.
