Abstract: A discrete Hartley transform (DHT) -based receiver model for orthogonal frequency division multiplexing (OFDM) systems was proposed. Its principle has been analyzed in detail, which showed that the performance of the proposed receiver model was the same as that of the conventional discrete Fourier transform (DFT) - based receiver in AWGN channel. And then simulation verified that. In the new receiver model a parallel processing mode was adopted. And so, low computational complexity, high processing speed and easy implementation with DSP were obtained in the meantime.
