On the New CCSDS Standard for Space Telemetry: Turbo Codes and Symbol Synchronization

A turbo code has been included in the new CCSDS channel coding standard for space telemetry. Many future missions with critical link budgets will benefit of its large coding gain. In this paper, the properties of this turbo code are analyzed for symbol synchronization recovery, where transition density is essential. Key parameters like transition/symbol probability and run-length distribution are studied and compared against practical requirements. Critical working conditions are individuated and discussed. It is shown that, thanks to the interleaver action, turbo-encoded sequences have very good properties in terms of randomness.
