Abstract :
The minimum mean-squared-error (MMSE) linear multiuser detector is popular because of its good performance and amenability to adaptive implementation. However, there are circumstances in which the linear detector that minimizes the 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
