Abstract
Recursive formulations of the moving-window discrete Fourier transform (DFT) are well known, However, recursive versions of other useful dis crete transforms, like the moving-window discrete cosine transform (DC T), discrete sine transform (DST), or discrete Hartley transform (DHT) , have not been developed so far, In this paper, second-order recursiv e expressions for the DCT, DST, and DHT, intended for real-valued wind owed sequences, are presented.
