@article{Tadrous2010PowerCF, title={Power Control for Maximum Throughput in Spectrum Underlay Cognitive Radio Networks}, author={John Tadrous and Ahmed Sultan and Mohammed Nafie and Amr El-Keyi}, journal={ArXiv}, year={2010}, volume={abs/1002.1584} }

We investigate power allocation for users in a spectrum underlay cognitive network. Our objective is to find a power control scheme that allocates transmit power for both primary and secondary users so that the overall network throughput is maximized while maintaining the quality of service (QoS) of the primary users greater than a certain minimum limit. Since an optimum solution to our problem is computationally intractable, as the optimization problem is non-convex, we propose an iterative…

This work presents a proposition to simplify the optimization of the power assignment for multiple-input-multiple-output (MIMO) systems in cognitive radio (CR) networks and finds that MMTPA outperforms EPA and IPC in the minimal throughput among all SUs.

This work investigates the effect of rate-splitting on the rate region for two cases of a multiple access primary network with N transmitters and determines the optimal rate- Splitting that maximizes the sum throughput of the primary network and the secondary link subject to a constraint on primary rate.

A necessary and sufficient condition to determine which primary signal that the secondary receiver can decode without degrading the range of primary achievable sum rates is provided and it is shown that the probability of having at least one primary user satisfying this condition grows with the primary signal to noise ratio.
