Direct split-radix algorithm for fast computation of type-II discrete Hartley transform
In this paper, a novel split-radix algorithm for fast calculation the discrete Hartley transform of type-II (DHT-II) is intoduced. The algorithm is established through the decimation in time (DIT) approach, and implemented by splitting a length N of…
