This thesis is focused on the analysis of false alarm probability of the CLTU (Communications Link Transmission Unit) tail sequence and it has been carried out with the European Space Research and Technology Centre (ESTEC-ESA). The Consultative Committee for Space Data Systems Standard (CCSDS) is taken as a guideline for the definition of specifications. The main focus is on studying false alarm probability of the CLTU tail sequence when used with Low-Density Parity-Check (LDPC) error correcting codes, decoded through iterative algorithms, such as the Sum-Product Algorithm, the Min-Sum Algorithm and the and Normalized Min-Sum Algorithm.

Questo elaborato `e incentrato sull’analisi delle probabilit`a di falso al- larme della tail sequence del CLTU (Communications Link Trans- mission Unit) ed `e stata realizzata con il Centro Europeo di Ricerca e Tecnologia Spaziale (ESTEC-ESA). Il Consultative Committee for Space Data Systems Standard (CCSDS) viene preso come linea guida per la definizione delle specifiche. L’attenzione si concentra sullo studio delle probabilit`a di falso allarme della tail sequence CLTU quando viene utilizzata con codici di correzione degli errori LDPC (Low-Density Parity-Check), decodificati attraverso algoritmi iterativi, come l’algoritmo Sum-Product, l’algoritmo Min-Sum e l’algoritmo Min-Sum normaliz- zato. Le simulazioni e l’analisi delle prestazioni sono effettuate tramite MATLAB e altri software ereditati dal progetto NEXCODE

Abstract
This thesis is focused on the analysis of false alarm probability of the CLTU (Communications Link Transmission Unit) tail sequence and it has been carried out with the European Space Research and Technology Centre (ESTEC-ESA). The Consultative Committee for Space Data Systems Standard (CCSDS) is taken as a guideline for the definition of specifications. The main focus is on studying false alarm probability of the CLTU tail sequence when used with Low-Density Parity-Check (LDPC) error correcting codes, decoded through iterative algorithms, such as the Sum-Product Algorithm, the Min-Sum Algorithm and the and Normalized Min-Sum Algorithm.
