| Abstract: | The voice service is one of the most important applications in satellite communication. We put forward the proposal that uses multi-processor structure to design the multi-channel voice system. The system is designed by using several professors. It can resolve the signal processing and the voice data transfer. We use HPI interface and A/D interface to meet the data transfer among the several professors. The prototype test results show that this design scheme is reasonable and can meet the requirements of system applications. |
