  • Abstract
    The multiplicative complexity of the two-dimensional discrete Hartley transform (2D DHT) of size 2n*2n, where n is a positive integer, is determined. The method of deviation is based on linear congruences and a ring structure. The minimal number of real multiplications necessary to compute a length-2n two-dimensional discrete Hartley transform over the field Q of rational numbers is 22n+11-6(n-1)2n-8. DHT (2n; 2) has the same multiplicative complexity as a corresponding real data 2D-DFT.
