The effectiveness of small microphone arrays for in car use is investigated. These arrays are designed for speech enhancing at noise background within the cabin of a moving car. Speech and noise simulation based on designed mathematical algorithm of sound field modeling within a car cavity is applied for predicting effectiveness of the spatial-time(More)
As is well known, the problem of signal reconstruction may be reduced to estimation of coeecients of some signal decomposition. In the previous paper 1] we h a ve s h o wn, that optimal coordinate basis for this method must be formed from eigenfunctions of the Fisher's information operator (so-called PIC-basis). However direct usage of the PIC-basis is not(More)
The given paper is further development of papers [1] – [3], in which method of the Principal Informative Components (PIC) have been proposed. The PIC-method provides decreasing of estimation error in signal reconstruction problems. The method also can be used for problems of a source coding. PIC-technique is based on using of properties of(More)
