Abstract

Resource allocation problem in OFDM based CRNs has been widely studied under different settings in the open literature. A power allocation grouping scheme based on the interference channel gain, pulse shape and frequency distance is presented in Hosseini and Falahati (Power allocation grouping scheme considering constraints in two separate stages for OFDM-based cognitive radio system. In: Proceedings of the IEEE international conference on electrical information and communication technology (EICT), pp 1–6, Feb 2014) in order to improve capacity while the interference power for PUs stays at constant level. At the first stage, power is assigned to some groups based on the grouping scheme and at the second stage, the remaining power is allocated to others with water-filling algorithm.
