基于发送参考UWB信号的模拟自适应多用户检测器

An Adaptive Multiuser Detector in Transmitted-Reference IR-UWB Communication

通过构建一种用户伪随机PN码调制参考脉冲的TR-UWB信号,并根据最小均方准则提出了一种模拟的LMS反馈模板估计方法,充分利用了参考信号的波形和符号信息,可以有效的减轻噪声和多址干扰的影响。通过对性能的仿真分析表明:模板长度对IR-UWB检测性能是有影响。

By modulating the transmitted-reference with a pseudo-random code, an analog LMS detection based on minimum mean-square error criterion to suppress the interferences is proposed. The method uses not only the waveform of the TR signal, but also its symbol information. The performance is further analyzed and the width of integration window is discussed.
