| 摘 要： | 针对实际实现的DSSS系统采用的PN序列都是有限长、周期的情况,证明了单频干扰经过解扩处理后得到的加性干扰序列在时间上按照正弦规律变化,求出了正弦变化的频率,给出了求得其幅值的方法,并讨论了两种特殊情况。最后,仿真和实际系统验证进一步证明了结论的正确性。

| Abstract: | Since all PN sequences used in practical DSSS systems are periodic and have finite length, this paper proves that the result sequence of CW interference being despreaded varies according to sinusoid in time, its frequency and amplitude are derived, and two special cases are discussed. Simulation and practical system verification also show the validity of results. |
