This paper presents an ultra-low-power voice activity detection (VAD) system to discriminate speech from non-speech parts of audio signals. The proposed VAD uses level-crossing sampling for detection. useless samples in the signal are eliminated due activity-dependent nature this scheme. A 40 ms moving window with a 30 overlap is exploited as feature extraction block, within which output analog...

Level crossing rate, outage probability and fade duration of the SSC combiner output signal are determined in this paper. The presence of the Nakagami-m fading at the input is observed. The results are shown graphically for different variance values and decision threshold values. Key-Words: Diversity reception, Level Crossing Rate, Fade Duration, Outage Probability, Nakagami-m fading, SSC Combi...
