Abstract
To resolve the problem of voice activity detection in radio communication,considering the characteristics of short wave radio speech has low signal-to-noise ratio and complex noise typos,this paper presents a modified voice activity detection algo-rithm based on power spectrum entropy.The design of hangover and smoothness of power spectrum entropy are equipped to the algorithm.Several kinds of typical radio speech are used to evaluate the algnrithm.Experimental results show that this algorithm manifests outstanding performance in radio communication environments.关键词
