摘　　要：给出了一种基于滤波器组的多用户检测器.在发送端对数据进行综合,在接收端对信号进行分解,对分解的多路信号进行检测.该检测器结构简单,避免了矩阵求逆运算,其性能比传统多用户检测有较大提高.A multiuser detector based on filter banks is proposed in the essay. Data are synthesized at the transmitter, and signals are decomposed at the receiver. Multiuser detection is applied to each of the decomposed M channel signals. This detector is not only simple in structure, but also has the advantage of avoiding the computation of inverting matrix, and its performance is largely improved.
