Abstract

The invention discloses a simple and convenient calculation method for global large-scale deployment of IMT base stations on satellite lumped interference. The method comprises the following steps: uniformly sampling each simulation link to generate the distribution probability of an azimuth angle and a pitch angle of a simulation area pointing to a certain GSO satellite and the distribution probability of an azimuth angle and a pitch angle of an antenna main lobe of an IMT base station; calculating the distribution probability of the antenna gain of each interference link according to a Bayesian formula; after the interference power of each interference link reaching the GSO satellite space station is calculated, sampling simulation is carried out from a sample space by using a Monte Carlo method, the lumped interference power of each Monte Carlo simulation is calculated, and the interference probability of the ground IMT base station lumped interference satellite space station is determined according to an interference judgment criterion, so that whether the two systems are compatible or not is determined. According to the characteristics of large-scale simulation, accurate simulation of satellite interference in large-scale base station deployment can be guaranteed, simulation time is saved, and the method has high practicability.

Description

technical field [0001] The invention relates to the technical field of system-level spectrum compatibility simulation, in particular to a simple and convenient calculation method for aggregate interference of IMT base stations deployed globally on a large scale to satellites. Background technique [0002] Compared with the terrestrial mobile communication system, the satellite mobile communication system has the obvious advantages of wide coverage and no limitation of terrain conditions. Disasters play an irreplaceable role in damage to terrestrial communication infrastructure. [0003] At the same time, in order to meet the ever-increasing wireless broadband data and coverage requirements, as well as the IMT industry and mobile operators' increasing spectrum requirements for new services, many countries hope to add IMT signs in the middle and low frequency bands. The compatibility between IMT services and existing services is the key to determine whether a certain frequenc...
