摘要：

The minimum mean-squared-error (MMSE) linear multiuser detector [1-2] is popular because of its good performance and amenability to adaptive implementation. However, there are circumstances in which the linear detector that minimizes bit-error rate (BER) can significantly outperform the MMSE detector. We propose a low-complexity adaptive algorithm for approximating the minimum-BER linear multiuser detector.
