摘要
基于宽线性处理可以改善线性多用户接收机的性能以及仿射和迭代平均可以加快算法收敛的思想,提出了一种宽线性迭代平均仿射LM S算法,分析了算法在均方意义下的收敛性,给出了算法稳定条件和失调公式,以及算法应用于码分多址系统多址干扰抵消的效果.
Motivated by the performance of linear multiuser receivers can be improved by widely linear processing, and the convergence speed of stochastic approximation algorithm can be fasten by affine and iterate-averaging, this work develops a widely linear iterate-averaging affine LMS algorithm for DS-CDMA MAI suppression. Its mean square convergence has been analyzed, and its stability region and misadjustment have been found out. Simulation in MATLAB shows that the performance of the proposed algorithm.
