Paper Abstract

The fast capture of spread spectrum code is one of the key technologies of Direct Sequence Spread Spectrum (DSSS) communication. There are several traditional methods for the fast capture such as XFAST and AVERAGE. In this paper we propose a new algorithm based on the time domain samples and Binary search according the autocorrelation of the PN code. Firstly, signal's simple rate is reduced to a quarter of the chip rate with the received spread spectrum, and determined with a specific method, then the signal is divided into four parts by the local PN code and accumulated to a new sequence. Finally, the synchronous pseudo-code is captured with the correlation of the two new reference sequences. Experimental results demonstrate that the proposed algorithm significantly improves the efficiency in the capture of long Pseudo-Code code in DSSS, compared with traditional methods.
