摘　　要：多径衰落信道下的盲自适应多用户检测算法的运算复杂度通常都比较大,提出了一种基于MSWF和CMA的盲自适应多用户检测方法,该方法避免了矩阵求逆和信道估计运算,具有相对较小的运算复杂度。通过模拟实验比较了几种算法的误码率性能,结果表明,所提方法具有明显的优势。The computational complexity of the blind adaptive multiuser detection algorithm with multipath fading channel was usually high. In this paper, a fast blind adaptive multiuser detection method based on the MSWF and the CMA was proposed. This new algorithm had a low computational complexity without the computation of matrix inverse and channel estimation. The simulation results show that the proposed algorithm for multipath multiuser detection has the advantage than other algorithms in terms of the BER.
