| Abstract: | The application of discrete Hartley transform in OFDM is studied. A discrete Hartley transform based orthogonal frequency division multiplexing system model is proposed. The transmission performance on AWGN channel and computational complexity of the new model are analyzed. The new model performs as good as the conventional DFT based system on AWGN channel, but its computational complexity and time cost are much lower. Both the modulation and demodulation can be implemented with the same algorithm. |
