A Power Control Game Algorithm Based on Interference Temperature in Cognitive Radio

摘要

Aiming at the power control in cognitive radio, a power control game algorithm based on interference temperature is discussed, and non-cooperative power control game which is created by David Goodman is used. The efficiency function was mended, and we also designed a new pricing function with interference temperature. Compared with other power control game models, the simulation shows that the NPG-ITLP algorithm can improve the parteo efficiency, and guarantee the QoS of the secondary users as well as primary users. It also realizes resource allocation equality in cognitive radio network.
