| Abstract: | 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. |
