Review on Multichannel HR-NMF Modeling for Non-Stationary Signals
Ashwini V.Nandurkar | Shrikant J. Honade [2]
Abstract: Engineering in the technosevia era concerns with the high speed with clarity. It may be either in the signals or in the Images. Golden point is to achieve the accuracy and purity of output. In this paper we studied the signal processing for the part of NMF and multichannel. Along with this we found that numbers of researchers are still working with single channel signal system. The way of implementations of the researchers is different but final aim to achieve the noise free signals. In this paper we are trying to study the multichannel signals and its separation for better output without noise. Most of the researchers use filters and NMF. The observations and study of the various researchers shows that nonnegative matrix factorization (NMF) is noticeable in the spectrograms. This study will take a short review of existing system and will find out the strength and drawbacks of the studied system. This study of review paper will help to minimize the problems of existing system in the implementation phase of our new approach to words the multichannel HR NMF modeling for Non stationary signals.
