Preview Abstract
Resource allocation in two-path relaying OFDM systems is investigated in this paper. In particular, it is first formulated as an optimization problem with the aim of total transmit power minimization, and is then decomposed into bit loading, subcarrier set allocation and source rate assignment issues. These issues are then solved separately, and a suboptimal algorithm is obtained. Simulation results demonstrate the effectiveness of the proposed algorithm under various system configurations through comparing it with the existing schemes with and without subcarrier pairing in traditional one-way relaying OFDM systems.
