摘要
自适应多用户检测器没有充分利用多用户信号特点 ,为此 ,提出联合式自适应算法 ,以接收信号作为参考信号 ,而自适应滤波器的输入信号变为各用户扩频序列的采样值。分析和仿真结果表明 。
Considering that traditional adaptive multi user detectors havent made full use of the character of multi access signals, a new algorithm of joint adaptive multi user detection is put forward. In this algorithm, the received signal is used as the reference signal, and the input of adaptive filter changes into the sampled value of each users spread spectrum serial. Analysis and Simulation results show that this kind of detector has faster convergence rate and better anti near far impact ability, so it has good potential for practical applications.
