Robust Power Allocation for OFDM-Based Cognitive Radio Networks: A Switched Affine Based Control Approach

In this paper, we investigate the robust power allocation issue in orthogonal frequency division multiplexing-based cognitive radio networks (CRNs) with unavoidable uncertainties (channel perturbations and variable environment). In this case, to control the performance degradation due to the uncerta...
