I'm looking to prove circular convolution using the Discrete Hartley Transform. I saw an old thread on this forum where someone had got it working: http://www.dsprelated.com/showmessage/130417/1.php I'm using the same formulations given by wiki: http://en.wikipedia.org/wiki/Discrete_Hartley_transform http://en.wikipedia.org/wiki/Hartley_transform (see the "properties" section in each case) There's some confusion about what X(-w) or Y(-w) means - is it just a flipped transform result sequence, or do you flip the sequence before the transform. Basically, I have two short real number sequences which I circularly convolve and correlate. I then calculate the DHT of these two sequences and check them against the DHT result using the wiki equations that combine source DHTs. I can't get a match with the DHT of either the convolution result or correlation result... Can anyone provide a worked example (Matlab / Octave?) so I can check where I'm going wrong?
