متن کاملA New Algorithm for Voice Activity Detection Based on Wavelet Packets (RESEARCH NOTE)
Speech constitutes much of the communicated information; most other perceived audio signals do not carry nearly as much information. Indeed, much of the non-speech signals maybe classified as ‘noise’ in human communication. The process of separating conversational speech and noise is termed voice activity detection (VAD). This paper describes a new approach to VAD which is based on the Wavelet ...
متن کاملEfficient Spectrum Sensing Using Discrete Wavelet Packet Transform Energy Detection in Cognitive Radio
The detection based on wavelet technique is commonly used in image processing in those applications which involve edge detection. In this approach proposed by Tian and Giannakis, wavelets were made use of for the detection of edges in the Power Spectral Density of wide-band channel for spectrum sensing. The edges in power spectral density serve as the demarcation separating the various spectrum...
