Method for evaluating the influence of position fluctuations on the performance of a millimeter wave drone communication system

Abstract

The application belongs to the technical field of air-to-ground millimeter wave unmanned aerial vehicle communication network, and discloses a method for evaluating the influence of position fluctuation on the performance of a millimeter wave unmanned aerial vehicle communication system, sets the air-to-ground millimeter wave unmanned aerial vehicle communication system, and randomly models the number of hovering unmanned aerial vehicles, three-dimensional positions, random fluctuations of the three-dimensional positions, and blockages in the communication link; calculates the available probability of a single unmanned aerial vehicle and the number distribution of available unmanned aerial vehicles in the system; calculates the blocking probability of the unmanned aerial vehicle-user communication link, calculates the probability distribution function of the blocking probability, obtains the functional relationship between the blocking probability of the communication link and the position fluctuation of the unmanned aerial vehicle; respectively calculates the reliable service probability and the coverage probability related to the link blocking state and the signal-to-noise ratio, and takes them as the indexes for evaluating the system performance, and evaluates the communication system performance under different unmanned aerial vehicle position fluctuations through the performance evaluation indexes. The application can simultaneously consider the reliability, effectiveness and low-cost operation of the communication system.
