In this paper, we address the transmission rate optimization problem for a multi-relay orthogonal frequency division multiplexing (OFDM) system with simultaneous wireless information and power transfer (SWIPT), where each amplify-and-forward (AF) relay does not consume its own energy. By introducing a subcarrier-pair factor, we provide the joint subcarrier-pair and power allocation scheme based on the Hungarian algorithm and Lagrange dual method to maximize the transmission rate. Simulations show that the proposed algorithm can perform better on information transmission rate than other algorithms.
