摘要： A DHT-based OFDM transmitter and receiver use discrete Hartley transform to implement multicarrier transmission. A transmission terminal (or a receiving terminal) of a transmitter and receiver comprises two IDHT (or DHT) processors and a diagonal processing device. The two IDHT processors make the DHT-OFDM system transmit the 2D modulation signal to increase the bandwidth efficiency. The diagonal processing device is used to diagonalize the circulant channel matrix into discrete memoryless subchannels, and thus only one-tap frequency domain equalizer can compensate the channel effects. Besides, the proposed DHT-OFDM transmitter and receiver are also compatible with a conventional DFT-OFDM system, and they can flexibly works with the conventional DFT-OFDM transmitter and receiver.
