A Method of Distributed Data Fusion Based on Orthogonal Wavelets

Abstract

Within the last decade, acquiring distributed signals from the same source and then aggregating them into a single signal has captured the interest of many scientists. The first goal of this communication is to introduce and provide a succinct description of VISA - a versatile interface of signal acquisition. Moreover, signals are spatially distributed. The interface is intended to become the kernel of a mobile system allowing the user to perform monitoring of some phenomena. As a second goal, the problem of information compaction by data fusion is also approached within the paper. Wavelets seemingly are suitable tools for extraction of common features from various signals and to compact them into a fused signal. Therefore, a method of data fusion based on orthogonal (Daubechies) wavelets, iterative deepening approach (from Artificial Intelligence) and some statistical criteria is briefly described as well.
