Research Of The Spacecraft Date-link Channel Encode Technology

Information encode is the key technology of Spacecraft information share and efficiency transmission of the new generation precision guiding missile, to improve the performance of it and the Spacecraft date-link standardization information design, it is necessarily and urgent to begin the research.The paper start with how to improve the Spacecraft date-link code standard,according to the date-link message system structure request, on the base of analysis the demanding of Spacecraft date-link system and message code, study channel encoding key technology, At first, analyse the date-link channel encoding principle and means, definitude the date-link channel encode and decode request and algorithm choose, iprove the turbo encode algorithm based on Spacecraft date-link; then, use the computer emulate the Spacecraft date-link channel transmission, design the emulate flatform, analysis the emulation consequence. The study of this paper have reference and technique support for constitute the new generation precision guiding missile's date-link information standard, have impress reference and guiding value.
