Paper Abstract

In this paper, we introduce a new class of discrete parametric trigonometric transforms. We establish the conditions of unitarity of the discrete parametric trigonometric transform matrices, by which we construct a wide range of orthonormal transform matrices. Analysis of proposed unitary trigonometric (cosine, sine and combined sine-cosine) transforms is performed, and efficient algorithms for their computation are developed.
