Resumen
In this article an analysis is carried out
regarding the amount of noise in the audio signals
belonging to the DAB (Digital audio Broadcasting)
system, simulated using the MatLab software. For this,
a comparison was made between the signals obtained
at the output of the DAB system with and without the
use of an adaptive filter, allowing to know to what
degree the signal quality improves when filtered. For
this purpose, measurement techniques such as the
BER (Bit Error Rate) and the signal-to-noise ratio in
different stages of the system were used and compared
by power variations through the AWGN channel in the
system, in this way a noise reduction in audio signals
that were filtered system, in this way a noise reduction
in audio signals that were filtered compared to
unfiltered signals.
