Introduction to Multitone Multiresolution Wavelet Analysis
Ahmed Muthana M. Nadhim

Abstract:
The aim of this study was to investigate the use of wavelet bases in multitone or multi-frequency perspective to replace the traditional fourier bases that suffers from high spectral overlap and poor stop-band attenuation. This introduction or tutorial is very useful for multitone modulation in communication systems and other applications where, the bandwidth requirements are quite strict. Wavelet analysis appeared in many pure and applied areas of science and engineering where they are developed independently in the fields of mathematics, quantum physics, electrical engineering and seismic geology. Therefore, wavelet theory generally is a unified framework that led to many new applications such as multiresolution analysis used in computer vision, subband coding developed for speech and image compression and time-frequency localization provided for analyzing non-stationary signals.

S.G.VENKATESH:
This paper gives the introduction part in a very good form. It gives a basic platform for the beginners who are eager to do research in the field of wavelet theory. It will be more useful to me if i get the papers of Daubecies work namely " Ten lectures on wavelets" and "compactly supported orthonormal wavelets" thanking u.
