一种新的基于最小二乘准则的超宽带多用户检测算法

本文通过由跳时码唯一确定的编码矩阵将超宽带无线多址通信信道模型建模为一种线性模型，提出了一种新的基于最小二乘准则的超宽带多用户检测算法。该算法把最小二乘准则公式： 写成矩阵形式并且利用矩阵Moore-Penrose逆递推公式实现的自适应递推算法直接对编码矩阵进行更新，从而得到了一种新的超宽带多址通信自适应多用户检测算法。计算机模拟结果表明，该算法比传统的RLS算法有更好的收敛速度，并且相应的自适应多用户检测器比传统的检测器有更好的检测性能。

A Novel Multi-User Detection on LS in Impulse Radio UWB Systems

The systems of time-hopping BPSK in UWB were changed into a virtually linear model.The least square criterion was written into matrix form,and a new adaptive multi-user detection algorithm was proposed by using recursion of Moore-Penrose Inverse Matrix to the code matrix for each user which can be defined based on its unique TH sequence.Following the LS recursion of Moore-Penrose Inverse Matrix optimization procedures,the desired signal could be detected from the adaptive multi-user detection algorithm.Nume...
