摘要

线性异步去相关或最小均方误差(MMSE)多用户检测器的Gauss-Seidel迭代算法可以看作是一种线性软判决反馈多用户检测。基于这一思想，与计算相应相关矩阵逆的传统方案相比，可以使用更简单的管道结构实现线性去相关或MMSE检测器。通过这种流水线结构，可以减少大量的计算量。

A pipeline implementation of linear multiuser detector for asynchronous CDMA systems

The Gauss-Seidel iterative algorithm for linear asynchronous decorrelation or minimum mean square error (MMSE) multiuser detector can be viewed as a kind of linear soft decision feedback multiuser detection. Based on this idea, a linear decorrelating or MMSE detector can be implemented by using a much simpler pipeline structure compared with the conventional scheme of computing the inverse of the corresponding correlation matrix. Through this pipeline structure, a lot of computations can be reduced.
