A Method and Device for Interference Evaluation of Multiple Wireless Communication Systems

Abstract

The invention provides an interference assessment method and device of multiple wireless communication systems, and relates to the technical field of wireless communication. The method comprises the following steps: determining stray interference isolation degree between each two wireless communication systems according to a signal-to-noise deterioration threshold value, a receiver ground noise, bandwidth and stray indexes of each wireless communication system; determining the horizontal stray interference isolation distance between each two wireless communication systems according to the stray interference isolation degree; and constructing an interference isolation diagram according to the multiple wireless communication systems and the horizontal stray interference isolation distance between each two wireless communication systems; searching and traversing the shortest path of a node corresponding to each wireless communication system in the interference isolation diagram; assessing according to the shortest path so as to obtain the interference power of the interference loaded on any wireless communication system in the multiple wireless communication systems. By use of the interference assessment method provided by the invention, the interference loaded on any wireless communication system in the multiple wireless communication systems can be accurately assessed.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a method and device for evaluating interference of multiple wireless communication systems. Background technique [0002] At present, an interference assessment method between wireless communication systems is an interference assessment between two wireless communication systems. Under the general trend of co-construction and sharing, in most sites, multiple wireless communication systems coexist at each site, and each wireless communication system generally has multiple antennas radiating in different directions. Therefore, it is insufficient and inaccurate to only consider the interference isolation between two wireless communication systems and between two antennas of the wireless communication systems by using the prior art. Further, the interference isolation degree and isolation distance determined based on the interference evaluation results be...
