| Abstract(in English) | This paper proposes generalized a phase-shift keying (PSK) modulation and shows that an example of this generalized PSK is suitable for Viterbi equalizers. The proposed generalizations are as follows: 1) characteristics of the transmit filter does not need to be restricted to the Nyquist criterion; 2) the transmitted data sequence is rotated for every symbol in order to mitigate noise-correlation at the receiver. First, this paper shows a relationship between the conventional PSK and the generalized one. Next, this paper discusses disadvantages of Viterbi equalizers, e. g., a degradation in bit error rate performance both in the presence of sampling timing offset and on small time-dispersive frequency selective fading. Finally, computer simulation confirms that π/2 shifted binary PSK with narrow-band transmit filter, which includes offset QPSK for its special case, solves the above mentioned issues. |
