Power Control for Cognitive Radio Networks under Imperfect CSI Based on Game Theory
In this paper, the problem of power control for cognitive systems is studied via game theory. The objective is to maximize the sum utility of secondary users (SUs) subject to the primary users (PUs) interference constraints, the transmission power constraints of SUs, and the signal-to-interference-plus-noise ratio (SINR) constraint of each SU. In our earlier work, the problem was formulated as ...
متن کاملJoint Beamforming and Power Allocation Cognitive Radio Networks under Imperfect CSI
Traditional beamforming and power control algo-rithms in cognitive radio (CR) are based on the assumption of perfect channel state information (CSI) however; this may lead to performance degradation in realistic systems. In this paper, the problem of joint beamforming and power control is investigated in underlay CR networks with imperfect CSI. Our objective is to maximize the sum utility of se...
متن کاملCognitive radio based on Cooperative spectrum sharing with imperfect CSI
Cognitive radio is an emerging technology that aims for efficient spectrum usage. Cognitive radios have been proposed as a solution to the spectrum underutilization problem and have been proven to increase spectrum efficiency . However, in this we are analyzing the performance of the cognitive radio based on cooperative spectrum sharing. Here we propose a twophase spectrum sharing protocol whic...
متن کاملSpectrum Allocation Based on Game Theory in Cognitive Radio Networks
As a kind of intelligent communication technology, the characteristic of dynamic spectrum allocation of cognitive radio provides feasible scheme for sharing with the spectrum resources among the primary user and secondary users, which solves the current spectrum resource scarcity problem. In this paper, we comprehensively explored the cognitive radio spectrum allocation models based on game the...
متن کاملDownlink Channel Assignment and Power Control for Cognitive Radio Networks Using Game Theory
We consider a cognitive radio network in which a set of base stations make opportunistic spectrum access to support cognitive radios within their cells. As the spectrum of interest is licensed to the operator of a primary network, channel assignment and power control must be carried out in the cognitive network so that no excessive interference is caused to users of the primary network. Given t...
