[ 1 ] - راهکار جدید استخراج ویژگی مبتنی بر نمونه‌برداری فشرده در پردازش سیگنال‌های صوتی

In this paper, we present a Compressive Sampling (CS)-based feature extraction method for audio signals. In the proposed approach, the audio signal is firstly segmented by hamming windows and the Discrete Fourier Transform (DFT) of the samples is calculated within each frame. Then, the normalized values of the DFT coefficients of each frame are accumulated. At the next step, the second DFT is a...
