Cognitive radio is a promising technology, which can alleviate the problem of crowded bandwidth resource with low spectral efficiency. In this paper, we present a cross-layer approach for joint link scheduling and power control in cognitive radio networks, in order to make more efficient use of system resources. The principle behind this algorithm is to find a transmission scenario in which the network...
Link adaptation is an important issue in the design of cognitive radio networks, which aims at making efficient use of system resources. In this paper, we present a new method to solve the problem of joint rate and power control in cognitive radio networks by using game theory. The optimum rates and powers are obtained by iteratively maximizing each linkpsilas utility function. Simulation results...
