摘要: The wavelet transform has been developed in recent years and attracted growing attention from mathematicians as well engineers. In this introductory chapter, we would like to review briefly some basic concepts methods of new approach under the more general framework time-frequency analysis methods. We will discuss Fourier transform, short-time distributions, followed by a discussion theory its variations.
