Has proven the value of puting power, it also provides a professional level of symbolic putation, word processing, visual modeling and simulation and realtime control functions.The adaptive filter is an important part of statistical signal processing. In practical applications, does not have sufficient information to design a fixedcoefficient digital filter design rules in the normal operation of the filter change, so we need to study the adaptive filter. Those who need to deal with the signals generated by the result of the operation environment of unknown statistics or need to deal with nonstationary signals, the adaptive filter can provide an attractive solution, and its performance is usually far superior to the fixed filter design using the regular method . In addition, the adaptive filter can also provide nonadaptive methods can not provide a new signal processing capabilities.This course design is to use the powerful puting power of MATLAB software, the use of the RLS adaptive filtering algorithm microphone noise reduction. Aims to develop the way we use puters t
