Novel Algorithm

The capture of long Pseudo-Code code is the most important technology in spread spectrum system. we use XFAST,AVERAGE to solve this problem in old days. A new algorithm is proposed which based on the time domain samples and binary search according the autocorrelation of the Pseudo-Code (PN code) and improve the speed of the capture of long Pseudo-Code code in spread spectrum system. Firstly, received spread spectrum signal's simple rate is reduced to a quarter of the chip rate and determine with a specific method, then divide the local PN code into four parts and accumulated to a new sequence. finally, the synchronous pseudo-code is captured with the correlation of the two new reference sequences. Compared with conventional methods such as XFAST, capture time and precision are improved.
