| Abstract: | Spread spectrum technology is widely used because of its own excellent performance, its main application is a military anti-jamming communications, direct sequence spread spectrum communication system （DS-SS）is most widly used Jn this area.Based on m-sequence DS-SS,this paper analyses its various anti-jamming capability in detail, indicates that relativity and randomness of m-sequence is the direct cause of anti-jamming, brings forward finding the ideal spreading codes to enhance the improvement of anti-jamming capability. |
| Keywords: | Spread Spectrum Anti-jamming M-sequence |
