直接序列扩频相关峰的概率分布

Probability Distribution of DS/SS Coherence Crest Value

本文根据移动通信中多径传播的特点,研究了“扩频死区”出现的概率,以及正常扩频和“扩频死区”两种条件下扩频相关峰的条件分布密度。最后,从扩频概率增益的角度将其抗干扰性能作了比较,得出了一些有益的结论。

Based on the characteristics of multipath propagation in mobile communication, the probability of the “DS/SS dead band” and the conditional distributions of the coherence crest value in the cases of the normal DS/SS and the “DS/SS dead band” are presented in this paper. Finally, the anti-interference performance is compared with probability gain.
