• 3 a novel recursive least - square ( rls ) blind space - time receiver algorithm based on the constrained condition , which can completely avoid the matrix inversion introduced into by constraints ( comparing with the normal rls ) , is proposed for multi - path slow fading cdma channels . the computational complexity of this method is not only lower than that of the normal rls , but also lower than that of both lms and ls blind space - time receiver methods that are realized based on the rosen ' s gradient projection . and the speed of convergence of the presented rls blind space - time receiver algorithm is better than that of both lms and ls blind space - time receiver methods
  3 、针对多径慢衰落信道下ds - cdma盲空时接收机中线性约束二次规划问题提出一种新的递归最小二乘算法，该算法完全避免因约束而引进的矩阵求逆运算(相对于常规的递归最小二乘算法) ，不但运算量比常规的要低，而且比基于rosen梯度投影实现的最小均方( lms )与最小二乘盲空时接收机算法还低，且收敛速度比基于rosen梯度投影实现的最小均方( lms )与最小二乘盲空时多用户检测都好，将提出的新的递归最小二乘算法与提出的数据选择方案结合起来可以进一步降低其运算量，具有很大的实用价值，最后通过仿真实验进一步分析了其性能。
