| Abstract: | The main target of the paper was to analyze the situation about the use of wireless spread spectrum technique in the CBTC System.Through the comparison of the anti-jamming capability with the Communication System of direct-sequence （DS） spread spectrum and frequency hopping（FH） spread spectrum,DS-FH spread spectrum technique was raised up to onboard/ground Communication System,and its anti-jamming performance was discussed. |
