With the social progress of industrial production, all kinds of noise pollution is
more and more serious. The current widespread use of the simulation of the noise
reduction method can not meet the requirement has, and further research will toward
to digital signal processor and related algorithm for technical support digital noise
reduction technology development.Filter design in digital signal processing plays an
extremely important role,. Matlab is powerful, easy to learn, programming efficiency,
which was welcomed by the majority of scientists. Matlab also has a particular signal
analysis toolbox, it need not have strong programming skills can be easily signal
analysis, processing and design. Using MATLAB Signal Processing Toolbox can
quickly and efficiently design a variety of digital filters. In the past few decades,
based on the noise of the microphone is always the people to pay attention to
eliminate the subject. And in numerous algorithm, LMS algorithm based on the
generalized update filter weight value side-lobe eliminate most widely used the
structure. More noise reduction design mainly through the microphone to realize
adaptive filter. This article apply LMS algorithm in MATLAB realize adaptive filter,
the design and implementation. In MATLAB established digital noise reduction
system model, and the model for use of MATLAB language programming, the
simulation results show that the designed to signal mix in some environmental noise
noise reduction, and the effect is far higher than analog noise reduction technology.
