摘　　要：量子信号处理是一种基于量子检测原理的信号处理框架.本文通过借鉴量子信号处理的思想,给出了一种新的线性多用户检测器:加权正交匹配滤波检测器.理论分析和仿真结果表明:新检测器只需要多用户系统中的扩频码已知,就可以在不同的工作环境下,通过灵活调整影响因子,分别实现与解相关检测器、匹配滤波检测器相同的性能;且新检测器的最佳性能与线性最小均方误差检测器的性能接近.Quantum Signal Processing is a framework based on the principle of quantum detection. Weighed Orthogonal Matched Filter Detector which is considered as a novel linear multi-user detector is presented by using the ideas from quantum signal processing. Through adjusting impact factors under various environments, not only can the new detector achieve the same performance as the decorrelator and the matched falter with the same knowledge about the PN codes in multi-user system, it also can approximate the performance of linear MMSE detector.
