Cet article propose une modulation par déplacement de phase (PSK) à rotation de phase et montre que sa version à bande étroite est adaptée à l'égalisation de Viterbi. La PSK proposée présente les caractéristiques suivantes : 1) une mise en forme du spectre des filtres d'émission/réception ne doit pas nécessairement être limitée au critère de Nyquist ; 2) la séquence de données transmises subit une rotation pour chaque symbole afin de réduire la corrélation de bruit au niveau du récepteur. Tout d’abord, cet article traite d’une dégradation des performances du taux d’erreur sur les bits des égaliseurs de Viterbi en présence du décalage temporel d’échantillonnage ou sous un évanouissement sélectif en fréquence à dispersion temporelle. Ensuite, la simulation informatique confirme que la PSK binaire décalée de π/2 avec un filtre de mise en forme du spectre à bande étroite, qui inclut la QPSK décalée pour son cas particulier, résout la dégradation des performances mentionnée ci-dessus, en gardant une bonne efficacité spectrale égale à M-ary PSK.

Abstract: This paper proposes a phase-rotating phase-shift keying (PSK) modulation and shows that its narrow-band version is suitable for Viterbi equalization. The proposed PSK has the following features: 1) a spectrum shaping of the transmit/receive filters does not need to be restricted to the Nyquist criterion; 2) the transmitted data sequence is rotated for every symbol in order to reduce noise-correlation at the receiver. First, this paper discusses a performance degradation of bit error rate of Viterbi equalizers in the presence of the sampling timing offset or under time-dispersive frequency selective fading. Next, computer simulation confirms that π/2-shifted binary PSK with narrow-band spectrum shaping filter, which includes offset QPSK for its special case, solves the above mentioned performance degradation, keeping good spectrum efficiency equal to M-ary PSK.
