| 摘 要： | 首先研究了传统QPSK(Quadri Phase Shift Keying)扩频调制解调技术及其改进方案在干扰条件下的相关互调分量；然后针对软限幅透明转发器，建立了系统仿真模型，并给出性能仿真结果和分析结论。研究结果表明，改进方案能够显著改善存在干扰时软限幅条件下DSSS(DS Spreading Spectrum)系统的误比特率性能，从而改善了系统的抗干扰能力，对于应用DSSS技术的透明转发器卫星通信系统具有重要意义。

| Abstract: | Firstly the correlative intermodulation products of traditional QPSK system and modified algorithms are analyzed. Then in view of soft limited transparent transponder, the simulation model is built. The simulation results and the conclusion are presented. The results show that the modified scheme could improve the system performance and the anti-jamming capability notably. |
