Pour supprimer davantage les interférences d'accès multiple (MAI) dans le système à accès multiple à sauts de fréquence (FHMA), un nouveau type d'ensemble de séquences FH appelé séquence sans zone d'impact (NHZ) est proposé pour un système FHMA avec M-modulation FSK -aire (MFSK/FHMA) dans cet article. Les expressions pour les variables de décision sont dérivées pour le système asynchrone MFSK/FHMA avec un ensemble de séquences NHZ (MFSK/FHMA-NHZ) sous un modèle de canal à évanouissement lent de Rayleigh. Pour le cas particulier de M= 2, le taux d'erreur binaire analytique (BER) précis est dérivé en fonction du retard relatif maximum D et le nombre d'utilisateurs K par une méthode de fonction caractéristique. Les résultats théoriques validés par les simulations de Monte Carlo sont utilisés pour étudier la dépendance du BER moyen par rapport à D et à la K. La comparaison avec le système MFSK/FHMA avec modèle de réponse de Markov (MFSK/FHMA-Markov) montre que le système MFSK/FHMA-NHZ fonctionne mieux que le système de modèle de réponse de Markov tant que D est limité dans une certaine plage et en outre, le gain de performance augmente avec l'augmentation de la valeur de K.

Abstract: To further suppress the multiple-access interference (MAI) in frequency-hopping multiple-access (FHMA) system, a novel kind of FH sequence set named as no-hit-zone (NHZ) sequence, is proposed for an FHMA system with M-ary FSK modulation (MFSK/FHMA) in this paper. Expressions for the decision variables are derived for the asynchronous MFSK/FHMA system with NHZ sequence set (MFSK/FHMA-NHZ) under a slow Rayleigh-fading channel model. For the special case of M=2, accurate analytic bit error rate (BER) is derived as a function of maximum relative delay D and the number of users K by a characteristic function method. The theoretical results validated by Monte Carlo simulations are used to investigate the dependence of the average BER on D and K. Comparison with the MFSK/FHMA system with Markov hit pattern (MFSK/FHMA-Markov) shows that MFSK/FHMA-NHZ system performs better than Markov hit pattern system as long as D is restricted in a certain range and further, the gain in the performance increases with increase in the value of K.
