Description: 语音编码为信源编码，是将模拟信号转变为数字信号，然后在信道中传输。在数字移动通信中，语音编码技术具有相当关键的作用，高质量低速率的话音编码技术与高效率数字调制技术相结合，可以为数字移动网提供高于模拟移动网的系统容量。目前，国际上语音编码技术的研究方向有两个：降低话音编码速率和提高话音质。-Speech coding for source coding is the analog signal into a digital signal, and then in the channel transmission. In digital mobile communication, speech coding technology has a key role high-quality low-rate voice coding technology and high efficiency digital modulation technology, digital mobile networks for the provision of mobile networks is higher than analog system capacity. At present, the international speech coding technology, there are two research directions: reduce the encoding rate and the advancement of voice, then sound quality.
