Abstract
In this paper, we present a comparative study of fixed-point implementations of various feedback active noise cancellation (ANC) algorithms for headset applications. Different adaptive algorithms for wideband ANC were implemented on a TMS320C54x fixed-point DSP with single-precision words. The performance of each of them was tested and analyzed using different types of noise signals.
