Abstract

As far as receiver end of the communication system is concerned all the received signals are unpredictable and random in nature. The received signals may be of any type speech , computer data, video and music signals all carry useful information. The noise which is unwanted signal interfered with the useful signal in the medium most of the time and will very difficult to decode at the receiver end. The noise guassian noise which is present in all the frequency range is random in nature. So it has to deal properly otherwise false information is convey. Many methods are implemented earlier. In the present work we have implemented adaptive filter using adaptive algorithm Least mean square (LMS) and Normalized Least mean square (NLMS) to cancel or minimize the effect of the guassian noise present in the signals of Trumpet musical instrument. The work is done using matlab software. Wave form and result which include output PSNR is measured.
