Embodiment Construction

[0064] The present invention provides a power allocation method for a non-ideal millimeter wave wireless power supply communication UAV network. Based on the considered non-ideal millimeter wave wireless power supply communication UAV network, the energy coverage probability expression and information of the model are first obtained Cover the probability expression, and then get an optimization problem of power allocation coefficient according to the actual demand problem, then solve the optimization problem, and finally get the optimal power allocation coefficient that meets the requirements.

[0065] The receiver is a power division structure, that is, the user converts part of the collected signal into energy for its own use, and the other part is decoded as an information signal. Based on the ratio of the energy signal and the information signal, the distribution of the work division coefficient is used to find the optimal power division coefficient. Under the requirement o...

Abstract

The invention discloses a power distribution method of a non-ideal millimeter wave wireless power supply communication unmanned aerial vehicle network. The invention discloses a wireless power supplycommunication unmanned aerial vehicle network based on considered non-ideal millimeter waves. The method comprises the steps of firstly obtaining an energy coverage probability expression and an information coverage probability expression of a model, then obtaining an optimization problem of a power distribution coefficient according to an actual demand problem, then solving the optimization problem, and finally obtaining an optimal power distribution coefficient meeting requirements. The invention provides a method for solving the optimal power division coefficient of the millimeter wave unmanned aerial vehicle wireless energy supply communication network under the conditions of non-ideal hardware and non-ideal wave beams, and the efficiency of the network is improved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a power distribution method for a non-ideal millimeter wave wireless power supply communication UAV network. Background technique [0002] In a wireless power supply communication network, the deployed base stations and users, as well as the locations of other nodes in the network largely determine the characteristics of the entire network. Generally, the random geometry method is used to model the nodes in the network, so as to measure the performance of the network according to the derived expression that characterizes the performance of the system. Wireless power supply is to harvest energy from radio frequency signals in the environment to ensure the life of the node. But one of its relatively big disadvantages is that the efficiency is relatively low, and the collected power is generally at the milliwatt level. Millimeter wave has a highly direct...
