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.
