| Abstract: | This paper presented a optimum linear multiuser detector in terms of minimum mean bit error rate, and given a approximate method of solving the detector - method of training single perceptron. Numerical results show that 1) under ideal power control, in aspect of bit error rate, the optimum linear multiuser signal detector is better than the conventional and decorrelated multiuser signal detectors; 2) in aspect of "near far" resistance, the optimum linear multiuser signal detector is better than the conventional one, and is worse than the decorrelated detector. |
