Abstract :
Adaptive filter is one of the most important areas in digital signal processing. This paper seeks to use this area to remove noise from noise corrupted audio signals. An adaptive FIR filter with normalized LMS algorithm is designed to cancel the noise. A SIMULINK model is created and linked to TI TMS320C6711 digital signal processor through embedded target for TI C6000 SIMULINK toolbox and REAL-TIME workshop to perform hardware adaptive noise cancellation. The result is a noise free audio signal in the DSP board output.
