Abstract :
The generalized discrete W transform (GWT), which converts a length N+1 discrete signal to a length N sequence in the frequency domain, is defined, and its orthogonality is proved. The GWT can be computed via fast algorithms for the discrete W transform (DWT). Interpolation using the GWT is more accurate than interpolation schemes using other fast discrete sinusoidal transforms
