一种新的最小二乘盲空时多用户检测

A novel least-square blind space-time multiuser detection

提出了一种在多径码分多址信道下用Rosen梯度投影实现的最小二乘盲空时多用户检测方法 ,该方法的运算量与最小均方方法相当 ,但却具有递归最小二乘方法的收敛速度 .仿真实验表明 ,该方法性能良好 ,对空时处理在移动通信中的实用化具有积极的意义 .

The least square (LS) blind space time multiuser detection method realized by the Rosens gradient projection in multipath CDMA channels is presented, which has the same computation as the LMS method and has the convergent speed of the RLS method. Simulations illustrate that the performance of the method is good. It is of significance for space time processing to be realized in mobile communications.
