Application of digital signal processor to snore cancellation

This paper presents the application of a digital signal processor (DSP) to snore cancellation. The algorithm, which includes a finite impulse response (FIR) filter and the least mean square (LMS) method to tune the weights in filter, is adopted to design an anti-snore signal to destructively interfere the snore. Experimental results show the effectiveness of proposed method is up to 5-10dB.
