Multi-antenna system power optimization method based on wireless energy carrying technology

Abstract

The invention discloses a power optimization method of an antenna system based on wireless energy-carrying communication, which is applied to a base station serving a single-cell multi-user system. The method comprises the steps of receiving an uplink transmission pilot signal and residual electric quantity information of each terminal; carrying out channel estimation according to the uplink pilotsignal, and constructing an optimization model by taking the power consumption of each terminal in the data transmission process as a constraint condition and taking the maximization of the achievable rate of each terminal as a target; simplifying and solving the optimization model, and generating an optimal power division ratio of each terminal; according to the power division ratio, power distribution is carried out on each terminal; according to the method, the optimization model of the maximum reachable rate is established according to the received residual electric quantity information of the terminal and the uplink pilot signal; and the model is simplified, so that the solving complexity of the model is reduced, the solving time is further reduced, an allocation scheme for energy and information transmission of the terminal is quickly obtained when the terminal obtains the maximum reachable rate, and the spectrum utilization efficiency of the base station is improved.
