Abstract

The invention discloses a cognitive radio network frequency spectrum distribution method based on embedded particle swarm gaming. The method includes extracting the characteristic information of cognitive users; establishing a non-cooperative gaming model based on the characteristics of the cognitive users; resolving the gaming model by means of inner and outer particle swarm algorithms, namely, an embedded particle swarm algorithm; resolving and calculating the channel preference set of each cognitive user in the gaming model by means of the inner particle swarm algorithm based on the characteristics of the cognitive user; resolving the non-cooperative gaming model by means of the outer particle swarm algorithm based on the channel preference set of each cognitive user, and outputting the optimal frequency spectrum distribution result and a corresponding power matrix. Under the underplay frequency spectrum sharing manner, an optimal frequency spectrum distribution scheme is obtained by means of the embedded particle swarm algorithm. The method provided combines the game theory method and the particle swarm algorithm, the channel distribution and power control, rapidly distributes frequency spectrum sources, and moreover, maximizes the benefits of the cognitive users and the system profits within the maximum tolerable interference threshold of a main user.

Description

Technical field: [0001] The invention belongs to the technical field of wireless communication, in particular to a cognitive wireless network frequency spectrum allocation method based on embedded particle swarm game. Background technique: [0002] As a new type of communication technology, cognitive radio can perceive the surrounding radio environment, and through intelligent learning, it can adaptively change its parameters such as carrier frequency, transmission power and modulation technology, thereby improving spectrum utilization. In the field of radio communication, the management and utilization of spectrum resources is very important. The static spectrum allocation method commonly used in various countries is to allocate spectrum to licensed users, while other unlicensed users have no right to use it. When authorized users do not use spectrum, spectrum resources are wasted and spectrum utilization is low. At the same time, with the development of social informatiza...
