METHOD AND APPARATUS FOR SEPARATION OF IMPULSIVE AND NON-IMPULSIVE COMPONENTS IN A SIGNAL

摘要

Impulsive components and non-impulsive components within any time-domain signal such as audio, video, vibration, etc., are separated using wavelet analysis and sorting of wavelet coefficient sets according to statistical parameters of each respective coefficient set. Each entire coefficient set i s either included or excluded from each respective separated component based o n the statistical parameter. Thus, automatic, adaptive, flexible, and reliable separation of impulsive and non-impulsive components is achieved.
