摘要

研究了基于MMSE准则的多径信道CDMA信号盲估计问题。我们将异步CDMA模型构建到多输入多输出(MIMO)系统框架中，并开发了一种新的基于二阶统计量的盲均衡和用户分离算法来消除ISI和MUI。我们还给出了从接收信号中检测期望用户的条件。

Blind MMSE CDMA detection in multipath channels

This paper addresses the problem of blind estimation of CDMA signals in multipath channel based on MMSE criterion. We formulate the asynchronous CDMA model into the framework of multiple input multiple output (MIMO) system and developed a new blind equalization and user separation algorithm based on second order statistics to cancel ISI and MUI. We also give the conditions for detecting a desired user from the received signal.
