Abstract

The invention provides a spectrum resource self-allocation method, which comprises the following steps of: constructing a cognitive function-based game model through a Nash game model and a Stackelberg game model; constructing a water injection model based on a cognitive function through the game model based on the cognitive function in combination with a classical water injection algorithm; and solving the water injection model based on the cognitive function through distributed free iteration to realize self-optimization allocation optimization of spectrum resources. In iteration, a user caneffectively improve the convergence speed of the system by using an acceleration scheme. According to the invention, the optimization of the utilization efficiency of channel resources is realized, the channel rate of the scheme can reach the maximum value of the theoretical spectrum utilization rate, and good system performance can be obtained in different scenes. Frequency spectrum resources can be intelligently found and utilized, and the frequency spectrum resource utilization efficiency is improved to the maximum extent. An algorithm acceleration scheme is provided by utilizing the capability of predicting a competition result of a cognitive function, so that the operation speed can be greatly improved under the condition of not reducing the performance.

Description

technical field [0001] The present invention relates to the technical fields of wireless communication, spectrum resource allocation, and cognitive radio, and in particular to a spectrum resource self-allocation method. Background technique [0002] Nowadays, with the rapid growth of mobile communication services, wireless spectrum resources are facing a large shortage of problems. While there is a shortage of spectrum resources, there is also a large amount of waste of spectrum resources. Some frequency bands are relatively crowded, while some frequency bands are often idle. [0003] The existing network architecture can be divided into centralized and distributed. A distributed network has the advantages of low latency and low communication overhead. However, the distributed network also has the problems of system instability and low spectrum resource utilization. Contents of the invention [0004] Embodiments of the present invention provide a method for self-allocat...
