Co-existence analysis for interference of vehicle-borne UWB SRR system with FS system

To solve the co-existence problem of the 26G UWB SRR and fixed service systems, the paper considers the facts of random distributed distance between cars and SRR assembly rate, establishes a model for distance distribution, analyses the effects of facts including different rain attenuation, receiver antenna offset and antenna height to interference co-existence analysis, and computes the minimum protection distance for co-existence under different scenario. The final simulated results show the reduction of the minimum protection distance when considering certain facts in a real application scenario.
