Abstract An improved voice activity detection algorithm based on high order statistics is proposed. The algorithm can be applied in the 3rd generation mobile communication system. The simulation shows that Gaussian or non-Gaussian symmetric distributed noises in mobile background environment can be detected accurately and suppressed by the new algorithm.
