title = "Optimal joint sensing threshold and sub-channel power allocation in multi-channel cognitive radio",
abstract = "An optimal joint sensing threshold and sub-band power allocation is proposed for multi-channel cognitive radio (CR) system by formulating a mixed-variable optimization problem to maximize the total throughput of the CR while constraining the total interference to the PU, the total power of the CR, and the probabilities of false alarm and detection of each sub-channel. Based on the bi-level optimization method, the proposed optimization problem is divided into two single-variable convex optimization sub-problems: the upper level for threshold optimization and the lower level for power optimization. The simulation results show that the proposed joint optimization can achieve desirable improvement on the throughput with different sub-channel gains.",
