| Abstract: | 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. |
