Abstract EN
Multi-input multioutput (MIMO) technique provides a promising solution to enhance the performance of wireless communication systems.
In this paper, we consider antenna correlation at the transmitter in practical cognitive MIMO systems.
What is more, a game-theoretic framework is conducted to analyze the optimum beamforming and power allocation such that each user maximizes its own rate selfishly under the transmitting power constraint and the primary user (PU) interference constraint.
The design of the cognitive MIMO system is formulated as a noncooperative game, where the secondary users (SUs) compete with each other over the resources made available by the PUs.
Interestingly, as the correlation parameter grows, the utility degrades.
Nash equilibrium is considered as the solution of this game.
Simulation results show that the proposed algorithm can converge quickly and clearly outperforms the strategy without game.
