Abstract :
An algorithm is presented for direct acquiring PRN code based on sub-sampling, utilizing the auto correlation characteristic of the long period PRN code in DSSS (direct sequence spread spectrum) system. As decreasing signal-to-noise, the performance of algorithm is analyzed, and it is proved effectively by simulation, under sub-sampling.
