针对目前国内矿井下语音通信不够灵活或者通信系统成本高昂的情况,设计了一种低功耗、低成本,使用灵活高效的手持式语音通信终端。通过采用Zigbee自组网技术达到灵活搭建通信网络,多跳延伸通信距离,并且针对Zigbee由于传输速率低的而不能很好传输语音的问题,设计提出使用IMA-ADPCM算法进行语音压缩以保证高通话质量的前提下适应Zigbee的低传输速率的特性。经试验证明,本语音通信终端功耗可低至0.63瓦,在井下点对点通信距离可达到28.76米,语音信号传输平均误码率仅为1.95%。

In view of the present domestic underground voice communication inflexible or high cost of communication system, designed a kind of low power consumption, low cost, the use of flexible and efficient hand-held voice communication terminal. By using Zigbee ad-hoc network technology for flexible structures, communication network, the multiple hops extend the communication distance, and in view of the Zigbee transmission due to the transmission rate is low and not very good pronunciation problems, design IMA ADPCM algorithm - speech compression was proposed to ensure the high quality under the premise of to adapt to the characteristics of the Zigbee low transmission rate. Experiments prove that the voice communications terminal power consumption can be as low as 0.63 watts, underground point-to-point communication distance can reach 28.76 meters, the voice signal transmission average bit error rate is only 1.95%.

翻译成什么语言呢?去google翻译,或者你告诉我翻译成什么语言,我帮你拉!
追问
肯定是英语嘛,没特别说明就按照默认的来咯
机器翻得太生硬了,还是人工的好点
追答
哦。
