Research for anti-Jamming Capability of Direct Sequence Spread Spectrum Communications
BAI Chunhui
Abstract：This paper introduces the basic principle of direct sequence spread spectrum communication,the method for calculating the anti-jamming capability of direct sequence spread spectrum communication system for wideband interference, narrowband interference,single-tone jamming,uncorrelated interference is studied,the correlation between the suppression capability of direct sequence spread spectrum communication for multiple interference and processing gain is analyzed. It is proved that the processing gain of direct sequence Spread Spectrum system is proportional to the frequency spectrum expansion,the signal spectrum is wider,the processing gain is greater,the anti-jamming capability is stronger,and the technical measures to improve the anti-jamming capability of the direct sequence Spread Spectrum system are proposed.
