  • Abstract
    An adaptive minimum-BER linear multiuser detector called the least BER (LBER) algorithm, originally developed for BPSK modulation, is extended to 4-QAM modulation. Initial simulation results show that the proposed LBER detector has better performance, in terms of faster convergence rate and smaller steady-state BER, than the existing AMBER detector
