SPLIT-RADIX ALGORITHMS FOR LENGTH-p~m DHT

The split-radix 2/4 algorithm for discrete Hartley transform(DHT)of length-2~m isnow very popular.In this paper,the split-radix approach is generalized to length-p~m DHT.It isshown that the radix-p/p~2 algorithm is superior to both the radix-p and the radix-p~2 algorithmsin the number of multiplications.As an example,a radix-3/9 fast algorithm for length-3~m DHTis developed.And its diagram of butterfly operation is given.
