Abstract
To overcome the shortcoming that the carrier phase is difficult to restore,the unique method is selected to detect the multi⁃carrier frequency domain spreading code chip⁃level difference to overcome various test difficulties,and the receiver de⁃sign is simplified. This method can improve the ability of direct sequence spread spectrum system resisting the channel time selec⁃tive fading. The bit error rate performance of the multi⁃carrier frequency domain spreading code chip⁃level differential detection is analyzed in this paper theoretically. The simulation experiment results show this method can reduce the effect of inter⁃carrier inter⁃ference on code chip⁃level differential detection,and improve the performance of multi⁃carrier frequency domain spreading code chip⁃level differential detection with strong time selectivity in the channel.关键词
