A conventional single user detector is not optimum in the multiuser environment because the multiuser interference can not be modeled as an additive Gaussian process. Such a receiver is very vulnerable to the near far situation. The receiver that is optimum for multiuser environment has high complexity and requires a knowledge of the received signal energies. Various versions of the receiver that handle the near far situation have been proposed in the literature. In this work, an adaptive two stage scheme for a synchronous two user environment with unknown received energies is proposed. It consists of a, tandem of the conventional receiver and the interference canceler whose weights are adjusted by an adaptive algorithm. The error probability was evaluated analytically and it was shown that the receiver provides performance that is satisfactory in the near far scenarios.
