Abstract

The invention relates to an intelligent reflecting surface energy efficiency maximum resource allocation method based on safety communication, and belongs to the technical field of wireless communication. The method comprises the following steps: S1, constructing a multi-input single-output intelligent reflecting surface cellular communication system based on safety communication; s2, establishinga nonlinear and multivariable coupling resource allocation model taking maximization of the energy efficiency of the multi-input single-output cellular communication system as a target by consideringthe safety rate constraint of a user, the maximum transmitting power constraint of a base station and the continuous phase shift constraint; s3, converting a fractional objective function into an auxiliary variable parameter subtraction form by utilizing a Dinkelbach method, and then decoupling base station beam forming and reflection surface phase shift parameters according to an alternating iterative algorithm; and S4, converting the original non-convex problem into a standard semi-definite programming form, and carrying out solving by using a convex optimization tool. Simulation results show that the algorithm provided by the invention has higher energy efficiency and safety.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and relates to a method for allocating resources with maximum energy efficiency of an intelligent reflective surface based on safe communication. Background technique [0002] With the development of various communication technologies, the transmission rate of wireless networks has achieved a qualitative leap, such as large-scale multiple input and multiple output technology, millimeter wave communication technology, etc. However, the energy consumption and hardware cost of the communication network is an urgent problem to be solved [1]. Compared with traditional 4G technology, although 5G communication improves the efficiency of information transmission, it also increases system energy consumption and network construction costs. In recent years, intelligent reflective surface (IRS) has been proposed as a low-cost and energy-efficient method to solve the energy efficiency problem ...
