摘要 提出了一种简化的自适应差分脉冲编码语音压缩算法,压缩比为3:1,并将该压缩算法应用到C8051F410微控制器上。在满足低成本、低功耗及便于携带的条件下,完成了无线语音/数据通讯终端的硬、软件开发。实验结果表明,无障碍可靠通讯距离为182 m,MOS评价分为3.9,满足设计要求,语音通话质量满足要求。 This paper presents a simplified adaptive differential pulse code voice compression algorithms with compression ratio of 3:1 and the compression algorithm on the C805117410 mieroeontroller successfully. Under the conditions of meeting the need of low-cost, low power and easy to be portable, we completed hardware and software development of wireless voice and data communications terminal. The experimental results showed that the barrier-free and reliable communication distance is 182m, and MOS evaluation is 3.9, which meets the design requirements.
