Robust Power Allocation for OFDM Based Underlay Cognitive Radio Networks with Channel Uncertainties

Abstract

In consideration of all possible channel uncertainties without the assumption of perfect channel state information (CSI), a robust power allocation algorithm for underlay orthogonal frequency division multiple cognitive radio networks is presented. This algorithm can assign transmission power of each secondary user (SU) on each sub-carrier based on total… (More)
