HR-NMF MODELING FOR EXTERNAL NOISE REMOVAL OF NON-STATIONARY SIGNALS
Keywords:
Proposed System ModelAbstract
This paper implements formulations and algorithms of non-negative matrix factorization (NMF) for multichannel extensions. Herewe proposed multiple frequency model for the removal of background noise in the audio signals also we tried to analyze response of non-stationary signals. The performance of the proposed model is compared with the existing multiple frequency models using available datasets like babble, car, factory and train. Finally several real data are analyzed using both with MFCC HR-NMF and Without MFCC HR-NMF model. Weuse the usual traditional (LSEs) to compute parameters of the model during the execution and obtain the theoretical comparative good results also.
