REAL TIME ADAPTIVE FILTER
IMPLEMENTATION FOR SYSTEM
IDENTIFICATION AND NOISE ELIMINATION
Filters are the most important instrument that play a vital role in
signal processing application such as audio equalizers, image
processing etc. So in our proposed algorithm, we have utilized an
adaptive filter for system identification and noise elimination.
Identification of the system is necessary for the filter implementation;
this is accomplished using Least Men Square (LMS). Noise is a
feature that varies continuously if the device is used remotely, so we
require an adaptation technique to cater any kind of noise that can
affect our system and negate the effects of that noise for providing
a better signal quality. Mean Squared Error is reduced at a certain
interval of time as it adapts to the original signal. Our proposed
algorithm performed according to the desired expectations and can
be implemented in numerous audio applications.
