从轨道方程出发，对影响卫星光链路接收机带宽的主要因素———多普勒频移进行了研究。
The Doppler frequency shift, the main factor restricting the bandwidth of receiver in inter satellite laser link, with orbit equations is calculated.
由于水下信道的复杂性，节点之间的链路质量受到环境噪声干扰和多普勒频移，扩散等其他因素的影响。
Due to the complicated of underwater channel, the links between any nodes are subjected to noise interference, large Doppler shifts and spreads.
在移动环境下，ICI的产生主要由多普勒频移引起，同时，与CD MA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。
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.
