摘要

这项工作描述了一种基于电磁的多用户检测方法，该方法将干扰用户的信号视为隐藏数据。基于空间交替广义电磁(SAGE)算法，提出了一种适合于离散随机参数估计的新算法，并利用该算法推导出快速收敛的近最优多用户接收机。

EM and SAGE algorithms for multi-user detection

This work describes an EM-based approach to multi-user detection that treats the signals of interfering users as hidden data. We consider a new algorithm based on the space-alternating generalized EM (SAGE) algorithm appropriate for estimation of discrete random parameters, and we use it to derive rapidly-convergent nearly optimum multi-user receivers.
