In this paper, the authors propose a transceiver structure to reduce the interference between transmitting subcarriers and receiving subcarriers. Its performance in terms of Signal-to-Interference and Noise Ratio (SINR) is evaluated by both analysis and simulation and is incorporated into a recently proposed cooperation strategy for Orthogonal Frequency Division Multiple Access (OFDMA) systems to examine its performance under the realistic structure. The conventional Discrete Fourier Transform (DFT)-based approach will cause energy leakage in multipath channel with non-sample spaced time delays.
