Application research of wavelet threshold noise reduction in coal mine voice communicatio
According to characteristics of high-noise environment in underground coal mine, the paper put forward a new method which adds a wavelet threshold noise reduction module to voice communication terminals. The method improves soft and hard threshold of wavelet threshold noise reduction method, and con...
