Efficient calculation of digital convolution based on fast Hartley transform

Aleksandr B. Kokhanov, Victor V. Zakharov

Abstract


The paper describes an economic (from the computation cost viewpoint) algorithm for calculation of the cyclic digital convolution, and of the cross- and self-correlation functions of signals based on the fast Hartley transform. Application of the new algorithm makes it possible to diminish the computational complexity and the memory resource by one third as compared with the known version of the algorithm.
