Frame duration is an essential parameter to ensure correct application of multifractal signal processing. This paper aims to identify the multifractal nature of speech signals through theoretical study and experimental verification. One important part of this pursuit is to select adequate ranges of frame duration that effectively display evidence of(More)
This work provides new results for the separated encoding of correlated discrete memoryless sources. We address the scenario where an arbitrary number of auxiliary sources (a.k.a. helpers) are supposed to help decode a single primary source errorless. The rate-distortion analysis of such a system establishes the so-called many-help-one problem. We focus on(More)
