摘要
该文提出了基于高阶统计方法改进的自适应多速率话音激活检测算法,该算法可应用于第三代移动通信系统。实验证明:这种算法可以有效检测实际移动通信环境中高斯或非高斯对称分布的背景噪声。
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.
