The Integrated Transmission System Of Voice And Data Implemented By TMS320C54X

The task in this paper is designing a communication terminal which can transmit voice and data of the flight parameters through airborne analog radio transceiver. The system hardware is implemented by the high-speed DSP chip and other chips , such as A/D, D/A, AMBE2000, AT89C52 and PLD etc. Except the voice signal which can be compressed to 2. Okbps by the AMBE2000, the mux/demux to the data of the flight parameters and the digital voice, channel encoding/decoding, and modulation/ demodulation are all implemented by software on the conception of software radio. AT89C52 is used as coprocessor to achieve the control of system and the data exchange of the flight parameters.The significance of the flight parameters transmission, and the coretechniques of this system ----the voice compression encoding and DSPapplication are described at first, then the emphases of the paper are the analysis of the system operating principles and my research work which include the design of the system circuit and the software of the communication and control.
