in this paper the author considers a general method, based on time domain samples for spectral manipulation of time limited signals. first, the original signal is divided into some frames in the time domain. then, by presenting a suitable theoretical and computational algorithm, and using a method for improving the speed of convergence, we find the local bandwidth of each frame; thereby, each f...

In order to handle large data sets omnipresent in modern science, efficient compression algorithms are necessary. Here, a Bayesian (BDC) algorithm that adapts the specific measurement situation is derived context of signal reconstruction. BDC compresses set under conservation its posterior structure with minimal information loss given prior knowledge on signal, quantity interest. Its basic form...
