摘要: An improved Gabor wavelet is proposed in this paper, of which the two parameters have clear physical meanings. Among parameters, frequency parameter center symmetry wavelet's amplitude spectrum and equal to central window. The resolution factor can adjust support interval function time-frequency resolutions function. Also, maps signals from a time domain rather than time-scale domain. Moreover, an inverse transform proposed. Especially, realize lossless signal reconstruction without requirement for satisfy admissible condition. Finally, paper discusses differences between complete S transform, verifies them by real application.
