Noise Cancellation Using Adaptive Filters of Speech Signal by RLS Algorithm in Matlab

In wireless communication, if the property of signal are given, fixed filter are used by us. . but when the property of signals are unknown then we require to adjust the filter, this type of filter is called adaptive filter. It is use for remove the background noise. Here, in this paper we are introducing a new method for noise cancellation through RLS algorithm in matlab. It is more efficiencally and effectively from the other method of noise cancellation. The update filter coefficient are auto considered, so this method is very fast response and find estimated error and getting the original noise. Here we are using a speech signal as a input signal that should being contained many type of noise.
