| Abstract: | Speech is an essential part of satellite communication. The basic principle and performance of AC48304C-C Voice over Packet Processor is introduced briefly in the paper. According to the characteristics of Time Division Multiple Access （TDMA） satellite communication system, the design of software and hardware and the scheme of 4-channel voice compression system with this chip are given in detail. After setting up the satellite phonic communication platform with AC48304C-C, the result indicates that the project has good effect and the author presents some key information about the use of the chip from the practical experience with the backing of plenty of experiments and tests. |
