摘　　要：为了使共用同一频段的3.5 GHz固定无线接入系统(FWA)和C波段固定卫星业务(FSS)实现共存,就需要对这两个系统间的干扰进行分析。采用确定性计算方法主要研究了在建筑物密集但排列比较整齐的地形中3.5 GHz固定无线接入系统对C波段卫星地球站产生的同频干扰,给出了同频干扰的计算方法,并进行了仿真分析,从而验证了在这种地形下实现两系统干扰共存的可行性。To realize the coexistence of 3.5 GHz fixed wireless access（FWA） system and C-band fixed satellite service（FSS）,the interference between the two system needs to be analyzed,which are sharing the same band of frequencies.The co-frequency interference caused by 3.5 GHz FWA on C-Band satellite communication earth station is researched with the detesministic algorithm.The algosithm for dealing with the co-frequence interfesence is given and simulated.It is supposed that the location is filled with intensively and evenly arranged buildings.The possibility of the interfersence coexistence between the two systems in such environment is verified.
