基于非合作博弈的认知无线电网络功率控制
Power control based on non-cooperative game for cognitive radio networks
摘要
Abstract
A novel multi‐user power control model based on non‐cooperative game theory was pro‐posed with restraint factors as delay and traffic sensitivity .In order to mitigate the influence on algo‐rithm stability by channel sensing uncertainty ,the m‐norm approach was used to model uncertainty of channel sensing ,and then power control model was transformed to optimization problem with con‐straint conditions .A robust power allocation algorithm was proposed .Simulation results indicate that the proposed pow er control algorithm has faster convergence speed than existing algorithms ,mean‐w hile ,the system utility value remains high w hen the channel sensing uncertainty is increasing and secondary user could obtain higher power efficiency ratio with lower transmitting power .关键词
