摘要
阐述了自适应多用户检测的基本原理,提出了一种基于自适应共轭梯度(CG)算法的自适应MMSE多用户检测算法,推导了算法的迭代公式并进行了计算机仿真.仿真结果表明,与LMS算法、RLS算法相比,CG算法具有良好的性能.
The principle of adaptive MMSE multi-user detection algorithm is expatiated on in this paper. An adaptive MMSE multi - user detection algorithm based on CG is proposed. Its iteration formula is deduced and the algorithm is simulated by Matlab. The simulation shows that the performance of the algorithm is better than that of LMS and RLS.
