| Abstract: | In a spread spectrum communication system,the realization of the system function needs fast acquisition to the spread spectrum signal,which is also one of the vital technologies and an important anti-jamming method.In the beginning of this paper,we describe the principles of the fast acquisition to the spread spectrum signal based on the FFT;then focused on the problems in the realization,we present a new algorithm of the FFT fast acquisition using mean correlation processing.The algorithm was described in ... |
