| Abstract(in English) | π/4 shift QPSK scheme is widely used in several kind of mobile communication systems because of its excellent bit error property. However, it also has a problem that the undesired interference spectrum yields at the outside of the assigned frequency band when a non-linier amplifier is used. Ternary phase shift keying (TPSK) has not been focused upon until now because it is not suitable for transmitting binary information signals. However, it has theoretically excellent features for mobile communication systems, that is,it has splendid error rate characteristics and minimum amplitude fluctuation among all of the PSK schemes. The latter feature is very appealing for usage in mobile terminals in which non-linear amnlifiers have to be used. A new class of convolutional codes is proposed in order to use the TPSK scheme in practical systems. The coded TPSK scheme with the new convolutional code improves the amolitude fluctuation with the same error rate characteristics as the BPSK or QPSK schemes with conventional convolutional codes. |
