摘要: 提出一种基于离散Hartley变换的OFDM接收机模型,分析了其工作原理和性能。理论分析与仿真结果表明,该模型与基于离散傅里叶变换的OFDM接收机在加性高斯白噪声信道下具有相同的接收性能。该模型采用并行处理模式,具有算法复杂度低、时效性高、易于DSP实现的特点。

关键词: 正交频分复用, 离散Hartley变换, 离散傅里叶变换

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.

Key words: orthogonal frequency division multiplexing, discreteHartley trans-form, discrete Fourier transform
