In order to improve the reliability and security of direct sequence spread spectrum （DSSS） system, this paper applied the real chaotic sequence as spread spectrum sequence in DSSS system, analyzed its performance from three aspects including bit-error-ratio, anti-interception performance, and the system parameter detection. The results show that the DSSS system based on real chaotic sequence has similar bit-error-ratio performance compared with traditional DSSS system. Moreover, the DSSS system based on real chaotic sequence has lower probability of interception, and higher concealment, which is more suitable for the safety and security transmission of information.
