摘要：

In this paper, an Multicarrier modulation (MCM) tranceiver based on discrete Hartley transform (DHT) is investigated. Instead of conventional discrete Foruier transform (DFT), DHT is an alternative orthogonal basis with real-valued operation. However, the DHT can not directly diagonalize the multipath fading channel due to its inherent property. To deal with this problem, we devise a DHT-based OFDM architecture that can perfectly diagonalize the channel matrix base on the complementary property of DHT matrix and channel gain symmetric features. In addition, two-dimensional complex signaling, quadrature amplitude modulations (QAM), can also be applied to the proposed structure for bandwidth efficient transmission. Finally, numerical simulations have shown the validity of the proposed DHT-based OFDM system.
