Abstract
The high complexity of the maximum likelihood (ML) multi-user detection (MUD) restricts its application. The linear detector is a suboptimal algorithm with lower complexity, which is also the basis and criterion of many other algorithms, such as interference cancellation algorithms and adaptive receiver. In order to avoid the stochastic matrix inversion, which is the critical part of the conventional detector, a novel simplify algorithm, which has the same performance compare with the conventional detector but lower complexity, is proposed in this paper. And lower complexity linear equalizers can be derived by using the similar method.
