N2 - Spread spectrum communication system with high bit rate, has bad performance of acquisition sensitivity, since the coherent integration time is short. The bad performance can be improved by the method of non-coherent integration processing after coherent integration. But in low SNR environment, the performance is not satisfying because of the large SNR loss of non-coherent integration. This paper describes a new acquisition method. The method is to pre-process the coherent integration results before non-coherent integration. This measure can effectively improve the sensitivity performance because it has the merit of increasing the time of coherent integration. The efficiency of this method is proved through simulations.
