Résumé

Ce papier présente les résultats d’une étude sur la qualité de reception d’un radio ‘frequency hopper’ en présence de signaux parasites. Différentes methodes de corrections sur la perte de donnés fut analysées. La qualité accoustic fut mésuré subjectivement en déterminant la réaction des écouteurs en simulant la perte et correction de données en presence de signaux parasites variées.
