Communication systems have the challenge of accommodating many users in a small area. With the advent of spread spectrum, and hence, Code Division Multiple Access (CDMA), fixed bandwidth was used to accommodate many users by making use of certain coding properties, modulation techniques and...

Multiuser Detection (MUD) is the estimation/demodulation of transmitted bits in the presence of Multiple Access Interference (MAI). Matched filter-based conventional detectors treat the MAI as Additive White Gaussian Noise (AWGN). However, MAI has a nice correlative structure that is quantified...
