| 摘 要： | Hartley变换不仅等效于富氏变换 ,其正逆变换又具有相同的形式 ,而且在实序列数据处理中仅需用到实运算 ,在存储量和复杂性上要比富氏变换更经济更有效。针对一维及二维离散 Hartley变换分别建立了其修正循环卷积特性定理。籍此可得计算循环卷积的快速 Hartley变换法。

| Abstract: | Being fully equivalent to the Fourier transform and its direct and inverse transform possessing the same form, the Hartley transform which involves only real operations is more economical and efficient than the Fourier transform. This paper derives the modified cyclic convolution properties of Discrete Hartley Transforms (DHT), upon which the fast Hartley transform method for computing cyclic convolutions is obtained. |
