Cet article propose une méthode d'acquisition synchrone utilisant la cartographie de corrélation par détection à séjours multiples prenant en compte la pénalité de fausse alarme dans les systèmes M-ary/SS. Dans le procédé, tout d'abord, la valeur de corrélation entre un signal reçu et chaque séquence attribuée dans un système M-ary/SS sur une courte durée est calculée pour chaque phase et stockée dans le mappage. Deuxièmement, la valeur de corrélation maximale de chaque phase dans la cartographie est sélectionnée et organisée, puis la première phase synchrone probable est décidée par la valeur maximale de ces valeurs. Simultanément, la démodulation des données démarre. Ensuite, pour reconnaître la phase synchrone, c'est-à-dire prendre en compte la pénalité de fausse alarme, les valeurs de corrélation sont calculées sur une durée plus longue, et la deuxième phase probable avec une fiabilité élevée peut être obtenue par suppression du bruit au niveau du signal. Enfin, si la deuxième phase synchrone est différente de la première, la seconde est réinitialisée. Grâce à ce procédé, un temps d'acquisition court et une fiabilité d'acquisition élevée peuvent être obtenus. L'amélioration du temps d'acquisition et les valeurs de combinaison optimales du temps de séjour, qui est la durée nécessaire au calcul de la corrélation, sont présentées pour plusieurs conditions en M-ary/SSMA asynchrone.

Abstract: This paper proposes a synchronous acquisition method using correlation mapping by multiple-dwell detection considering false alarm penalty in M-ary/SS systems. In the method, first, the correlation value between a received signal and each assigned sequence in an M-ary/SS system in some short duration is calculated for each phase and stored in the mapping. Second, the maximum correlation value of each phase in the mapping is selected and arranged, then, the first probable synchronous phase is decided by the maximum one in these values. Simultaneously, data demodulation starts. Next, to recognize the synchronous phase, i.e., as considering false alarm penalty, the correlation values are calculated in longer duration, and the second probable phase with high reliability can be obtained by suppression of noise to signal level. Finally, if the second synchronous phase is different from the first one, the second one is reset. By this method, a short acquisition time and high reliability of acquisition can be achieved. The improvement of acquisition time and the optimal combination values of dwelling time, which is duration to calculate the correlation, are shown for several conditions in asynchronous M-ary/SSMA.
