Abstract：Absrtact The minimum mean square error(MMSE)detection algorithm is an algorithm that can achieve near optimal detec-tion performance in large-scale multiple input multiple output(MIMO)systems,but it involves the inversion of high-dimensional matrices,which has high complexity,so it is not suitable for application in practical projects.To solve this problem,this paper pro-poses a pretreatment Richardson(P-RI)iterative algorithm based on the idea of matrix blocking and Richardson(RI)algorithm.The algorithm first constructs a new form of linear iteration based on the idea of matrix blocking,and then preprocesses the Richard-son algorithm with this linear iteration,which effectively improves the convergence speed of the algorithm.Experimental results show that compared with the existing RI algorithm,the detection performance of this algorithm is better.
