An improved adaptive multi-rate voice activity detection algorithm based on high order statistics method

  • 摘要: 該文提出了基于高階統(tǒng)計(jì)方法改進(jìn)的自適應(yīng)多速率話音激活檢測(cè)算法,該算法可應(yīng)用于第三代移動(dòng)通信系統(tǒng)。實(shí)驗(yàn)證明:這種算法可以有效檢測(cè)實(shí)際移動(dòng)通信環(huán)境中高斯或非高斯對(duì)稱分布的背景噪聲。
    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.
