Game-theory-based spectrum allocation method, communication equipment and system

Abstract

The embodiment of the invention discloses a game-theory-based spectrum allocation method, communication equipment and a game-theory-based spectrum allocation system. The method mainly comprises that: a first user in a cognitive radio cell performs probability calculation on spectrum resources by utilizing a Bernoulli test, and judges whether a communication channel in the spectrum resources is occupied by the first user or not; if the communication channel is occupied by the first user, the first user calculates interference values Io generated on all available communication channels by the first user; after receiving the interference values Io, a receiver of a second user in the cognitive radio cell calculates interference values Id of users except the second user for the second user, and calculates a utility function U1 on each channel in the spectrum resources; and the second user extracts a communication channel corresponding to a value of the utility function U1 according to the value of the utility function U1 as the communication channel of the second user. The embodiment of the invention reduces electromagnetic interference among user equipment, and more effectively utilizes the spectrum resources.

Description
