摘　　要：根据伪噪声通信及伪随机码的相关特性,提出一种采用盲信源分离方法从伪码扩频信号中分离不同伪码序列的方法,并探讨该方法在CDMA监听系统中的应用。采用该分离方法能快速准确地分离和识别不同用户的伪码特征,来获得该用户的语音或数据信息,具有很好的应用前景。A method of seperating different pseudo-code sequence from pseudo-code spread spectrum signal by using blind source seperation is introduced,which is according to the cheracteristics of pseado-noise communication and pseudo-random code,and its application in CDMA monitoring system is discussed.The seperation method can quickly and accurately isolate and identify the pseudo-code feature of different users to obtain the user′s voice or data information.It has good application prospects.
