Abstract :
Three features for the discrete Hartley transform (DHT) transform are derived, including (1) the single/double data folding; (2) the constructive feature and (3) the data reusage. By using the CORDIC (coordinate rotations digital computer) algorithm, the DHT transform kernel hn×[cosθ+ sinθ] and conjugate kernel hn×[cosθ-sinθ] can be simultaneously determined. With these favorable properties, a novel systolic array design for the discrete Hartley transform is designed
