The purpose of this paper is to review some impor- tant models and methods in receiver design for mul- tiuser communication, and to outline some open prob- lems of potential interest to researchers with a sig- nal processing and information/communication theory background. We also present a new interference can- cellation technique that permits operation in an over- saturated regime, in which the number of users exceeds the number of signaling dimensions.
