Abstract :
To regulate transmit-power and enhance the total throughput, a novel transmit-power control game (TPCG) algorithm and M-TPCG algorithm which combines adaptive modulation and transmit-power control based on STBC OFDM- CDMA system are designed. The simulation results show that TPCG algorithm can regulate their transmitter powers and enhance the total throughput effectively, otherwise, M-TPCG algorithm can achieve maximal system throughput. The performance of the cognitive radio system is thereby improved obviously.
