| Abstract(in English) | This paper discusses about Viterbi equalization of a narrow-banded generalized phase-shift keying (PSK). The generalized PSK generalizes PSK modulation scheme on the following two points: the transmitted data sequence is rotated for every symbol; characteristics of the transmit filter does not need to be restricted to the Nyquist criterion. The authors previously reported that combination of the Viterbi equalizer and the generalized PSK mitigates an influence on sampling timing inherent in Viterbi equalization of the conventional M-ary PSK. This paper shows the following merits of this combination in addition to the previous considerations: 1) complexity of the Viterbi equalizer for the generalized π/2-shifted BPSK can be reduced in the absence of intersymbol interference; 2) a narrow-banded QPSK improves its sensitivity of the received signal, keeping the same frequency band of 16PSK. |
