Abstract :
This paper briefly presents a novel spectrum trading model for OFDMA-based cognitive radio systems. In this model, primary users are able to trade their spare subcarriers with secondary users. Specifically, each subcarrier is priced by primary users and sold to secondary users for better utilities. Also, the issues of pricing policies and market equilibrium are discussed.
