Paper Abstract

This paper introduces and evaluates a new algorithm for the computation of type-III discrete Hartley transforms (DHT) of length N = 2n. The length-N type-III discrete Hartley transforms can be decomposed into several length-16 type-III discrete Hartley transforms based on the radix-2 fast algorithm, and the length-16 type-III discrete Hartley transforms can be computed by first- order moments. It can save a lot of arithmetic operations and the computational complexity of the algorithms is lower than some existing methods. Moreover, this algorithm can be easily implemented.
