Abstract :
A novel approach to discrete interpolation of finite-duration real sequences using subsequences with the fast Hartley transform (FHT) is presented. It is shown that accuracy can be improved by decomposing the signal into an ordered set of subsequences. This development is also convenient because it permits the use of inverse fast Hartley transforms (IFHT) that are always the same size as the original FHT. This approach is also appropriate for the parallel processing of each subsequence
