The Development of Fast DST-II Algorithms for Short-Length Input Sequences

Krystian Bielak,
Aleksandr Cariow,
Mateusz Raciborski

Abstract: The subject of this work is the development of fast algorithms for the discrete sinusoidal transformation of the second type (DST-II) for sequences of input data of small length N = 2, 3, 4, 5, 6, 7, 8. The starting point for the development of algorithms is the well-known possibility of representing any discrete transformation in the form of a matrix–vector product. Due to the remarkable structural properties of the matrices of the DST-II transformation base, these matrices can be successfully factorized, whi… Show more
