This paper investigates various combined frequency interference in integrated and double-converted transceivers, and points out that the reason is the non-linearity of frequency mixer and amplifier.
研究了一体化二次变频收发信机中各种组合频率干扰的产生原因:主要是由于混频器和放大器的非线性。
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。
