OFDM-CR based Power Allocation Algorithm for Radio Systems

Abstract

As a matter of fact, both local and foreign academics have focused on the efficient power allocation method for discussion in recent years. With this in mind, the system power distribution method of cognitive radio combined with orthogonal frequency division technology is the subject of this paper's research aims. At the same time, the theoretical foundations of OFDM-CR will serve as the beginning point for this research, which will then focus on three existing power allocation algorithms. To be specific, they are water-filling algorithm, convex optimization algorithm as well as game theory algorithm. Based on the analysis, the paper then uses a table to compare various power allocation methods. Finally, according to the analysis, it makes logical recommendations based on the issues and considers how OFDM-CR technology may develop in the future. Overall, these results shed light on guiding further exploration of wireless communication of OFDM-CR based power allocation algorithms.
