Abstract

The invention relates to the technical field of communication, in particular to an energy efficiency power distribution method based on non-orthogonal multiple access in an MIMO system, which comprises the following steps: taking a user as a buyer and a base station as a seller; constructing the utility optimization model of the buyer and the utility optimization model of the seller; introducing an auxiliary variable to solve the optimal power purchasing strategy of the buyer; solving the optimal price formulating strategy of the seller by utilizing a convex optimization method; obtaining a user power value when the base station and the user play a game to achieve balance; and updating the auxiliary variable to calculate the optimal energy efficiency value of the user so as to obtain the energy efficiency value of the system. According to the method, only the benefits of a single user are considered, each user maximizes the energy efficiency of the user, and the algorithm complexity isreduced; and in the game process of the user and the base station, the power purchase value and price are adjusted according to the serial interference elimination residual factor, and the result iscloser to the optimal value.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an energy-efficient power allocation method based on non-orthogonal multiple access in a MIMO system. Background technique [0002] Mobile communication has achieved rapid development in recent decades, but people's demand for speed is still growing, and the spectrum resources available for wireless communication are not unlimited, so in 5G communication, there must be multiple users sharing The phenomenon of communicating on the same frequency band. In the multiple-input-to-output (Multiple-Input Multiple-Output, MIMO) technology adopted in 4G, the principle that any user in the same beam exclusively occupies a certain sub-channel is adopted. The Internet of Everything will inevitably lead to an explosion of data traffic, so the research on MIMO in 5G will be more in-depth. Non-Orthogonal Multiple Access (NOMA) technology can superimpose multiple users at the sending end...
