摘要：In this paper a module consisting of a Normalized Least Mean Square (NLMS) filter is modeled, implemented and verified on a digital signal processor (DSP) TMS320C7613 to eliminate acoustic noise, which is a problem in voice communications. However the acoustic noise cancellation (ANC) is modeled using digital signal processing technique especially Simulink Blocksets. The main scope of this paper is to implement the module onboard an autonomous DSK C6713 in real time, benefiting to the low computational cost and the easy implementation using Simulink programming. The needed DSP code is generated in code composer environment under Real Time Workshop. At the experimental level, implementation phase results verify that implemented module behavior is similar to Simulink model.
