The electro optic sampling system constructed with the multiple frequency phase shift scanning method was introduced.
分析了倍频移相扫描法的工作原理，介绍了用倍频移相扫描法构成的电光采样测量系统。
In a mobile environment, ICI is mainly caused by Doppler frequency shift. While, when combined with CDMA, Multiple Access Interference (mai) is another key factor affecting system performance.
在移动环境下，ICI的产生主要由多普勒频移引起，同时，与CDMA结合后，CD MA系统本身的多址干扰(MAI)也是影响系统性能的关键因素。
