Blind MMSE CDMA detection in multipath channels

Abstract

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.
