EnglishThis paper deals with the feasibility of the new receiver scheme for telecommand space links, based on the adoption of short low-density parity-check codes recently introduced in the standard. Being able to reduce significantly the required signal-To-noise ratio, these codes have an impact on the acquisition, tracking and synchronization issues. All these aspects have been faced, both theoretically and practically through the realization of a breadboard that implements the core elements of the on-board receiver, and is able to demodulate and decode uplink signals employing the new codes. The breadboard incorporates innovative solutions to cope with the acquisition and synchronization problems, and a pioneering implementation of non-iterative decoders based on the most reliable basis algorithm.
