基于干扰空间的盲自适应多用户检测器

The interference-space-based blind adaptive multiuser detector

在现有盲自适应多用户检测技术基础上,本文提出一种更具有实际应用价值的基于干扰空间线性MMSE盲自适应多用户检测器及其相应的基于干扰自相关矩阵C I跟踪算法。数学分析和仿真结果表明:与现有盲自适应多用户检测器相比,该检测器具有更低的实现复杂度、更快的跟踪速度和更强的健壮性。

A new interference-space-based blind adaptive MMSE linear detector and the corresponding tracking algorithm based interference correlation matrix is proposed. Analysis and simulation illustrate that the proposed blind multiuser detector has lower computational complexity, faster convergence and stronger robust with respect to the existing blind adaptive multiuser detectors.
