On a constructive representation of an orthogonal trigonometric Schauder basis for C 2π
Jürgen Prestin, Kathi Selig · Birkhäuser Basel eBooks · 2001
A particular class of orthogonal trigonometric Schauder bases for C 2π is given by periodic wavelet packet functions. These bases are of minimal growth of the polynomial degree. The focus of attention is their construction and the estimation of the Lebesgue constant. The corresponding approximation error is asymptotically optimal. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
