Modifsed Signal-Processing Algorithms Based on the Hartley Transform

Abstract

Abstract —Modified algorithms based on the Hartley transform (HT) are developed for solution of such important problems of digital signal processing as the calculation of cyclic convolutions and cross-correlation and autocorrelation functions. Data transmission based on orthogonal frequency division multiplex (OFDM) is considered. The proposed data-transmission system employs the HT as an algorithm forming orthogonal channel signals. The use of the developed algorithms simplifies conventional computational procedures and lowers the amount of required RAM. The results obtained can be applied for signal filtering and designing such advanced network standards as HiperLAN/2 and IEEE802.11a.
