摘要

提出了一种实现序列长度为2/sup m/的一维离散Hartley变换(DHT)的简单算法。该算法与Malvar算法(1987,1988)的乘法复杂度相同，其需要的乘法次数最少。然而，与马尔瓦尔算法相比，这种方法的优点是需要更少的加法。

New formulation of fast discrete Hartley transform with the minimum number of multiplications

A simple algorithm is proposed to realize a one-dimensional discrete Hartley transform (DHT) with sequence lengths equal to 2/sup m/. This algorithm achieves the same multiplicative complexity as Malvar's algorithm (1987, 1988) which requires the least number of multiplications reported in the literature. However, the approach gives the advantage of requiring a smaller number of additions compared with the number required in Malvar's algorithm.<>
