基于DCR标准的数字对讲机系统设计
The Design of Digital Intercom System Based on DCR Standard
摘要
Abstract
This article has studied the source code algorithm-AMBE algorithm and channel coding algorithm-punctured convolutional code in DCR standard. A digital intercom system complying with the DCR standard is designing using the ambe3000 vocoder and the digital private network mobile communication chip CMX7141 . And the simulation and experimental validation have been made. The test result indicated that, on the premise of guarantee the validity and reliability in communication,the system has the high quality of voice communication.关键词
