Minimizing Uplink Cellular Outage Probability in Interference Limited Rayleigh and Nakagami Wireless Fading Channels

We propose a game theoretic non-cooperative algorithm to optimize theinduced outage probability in an uplink cellular interference limited wireless Rayleighand Nakagami fading channels. We achieve this target by maximizing the certaintyequivalent margin (CEM). We derive a closed-form formula of the outage probabilityin Nakagami flat-fading channels, then we show that minimizing the induced outagefading probability for both Rayleigh and Nakagami channels is equivalent to maxi-mizing CEM. We present a non-cooperative power control algorithm using the gametheory framework. Through this non-cooperative game, we argue that the best de-cision in such an environment is for all users to transmit at the minimum power intheir corresponding strategy profiles. This finding considerably simplifies the imple-mentation of the proposed game.

Power Control Optimization Algorithm in Cognitive Radio Network

For cognitive radio environment needs of different users, A space-time diversity multi-carrier code division multiple access (OFDM-CDMA) technology architecture of the cognitive radio (CR) system is used, a novel non-cooperative power control algorithm and the price game (NPGP), in order to protect the economic interests of the spectrum of network providers, to achieve a fair and efficient allocation of spectrum resources have cognitive and improve spectrum efficiency. Simulation results show that the algorithm under the protection of the economic spectrum premise network provider benefits, both to ensure the fair and efficient allocation of spectrum resources, and achieve effective control of power users, system performance improved significantly.
