a constrained least mean fourth (LMF) criterion is proposed to construct a multi-user detection algorithm.The criterion is proven to have global minima in AWGN environment
and these stationary points can all decorrelate the multiuser signal as expected.The algorithm is a higher-order statistics type approach.Furthermore
an adaptive multiuser detector is obtained by using the method of the steepest descent.The detector has the virtues of global convergence and low computational complexity.In AWGN channel and multiuser environment
the simulation is studied and its results further demonstrate theoretic conclusion.
