Implementation of multiuser detection algorithms

Multiuser detection is a technique to detect multiple users at the same time using the Multiple Access Interference (MAI) of any multiple access communication techniques. This paper inspected the behavior of receiver for alteration in Bit Error Rate (BER) as change in the number of users over a channel with additive white Gaussian noise. Further verified the nature of receiver for alteration of BER against SNR for different number of users. Various techniques related to identification of a specific user in a noisy environment are discussed.
