Abstract:- This work presents a framework for wavelet-based representation of a given deterministic signal. We propose a method for matched wavelet based representation of the signal. Our method requires a signalconditioning step at each stage of the wavelet decomposition. The wavelet system designed in this work is biorthogonal. Both the signal-conditioning step and the wavelet system depend on the given signal. The proposed method is valid for signals having arbitrary spectra. The proposed method when applied to compression of different signals shows substantial improvement over.
