Subcarrier and Power Allocation for OFDM-Based Relay Cognitive Radio System

摘要：

　　In this paper, a suboptimal subcarrier and power allocation algorithm has been developed for the orthogonal frequency division multiplexing(OFDM)-based relay cognitive radio systems. The channel capacity of secondary users is maximized while keeping the total interference introduced to primary user less than a given threshold with a specified power. Compared with the other power allocation algorithm, the proposed method can achieve greater channel capacity and has a lower complexity.
