This paper focued on the power allocation for OFDM-based cognitive radio network.In order to maximize the transmission rate of secondary users and insure the interference introduced to the primary users is within a tolerable range,this paper proposed a power allocation scheme based on convex optimization theory.Simulation results show that this scheme can maximize the transmission rate with the interference and total power constraint.
