Abstract
In order to fair optimally allocate the limited cognitive radio resource
a cognitive radio system was developed based on STBC OFDM-CDMA network systems and a novel Nash bargaining solution named NBS of cooperative power control was adopted in this system
the transmitted power was dynamically adapted based on channel conditions
maxi-mal network throughput and power limits.Simulation results show that the novel algorithm can regulate their transmitter powers
fair optimally allocate radio resource.At the same power consumption
the network throughput is thereby im-proved obviously.
