摘要
本文根据已有的静止卫星网络之间的同频干扰计算方法 ,考虑非静止卫星网络下行数传的特点 ,提出了一种估算非静止卫星网络间下行数传的同频同向干扰的方法。该方法通过对离散化时间的仿真 ,可以从强度和频度两方面综合考察干扰的效果 ,从而能较全面地衡量上述的干扰情形。
According to the analysis method of existing co frequency interference between geostationary satellite networks and considering the characteristics of data transmission in down link of non geostationary satellite network,this paper proposes a method to evaluate co frequency and co direction interference for data transmission in down link between non geostationary satellite networks.This method can observe comprehensively the effect of interference from the two aspects of intensity and frequency through simulating separated time,thus can judge completely the above mentioned interference situation.
