一类重要的数字调制是相移键控（PSK）。三进制移相键控（TPSK）由于不适合传输二进制信息信号，迄今为止尚未受到关注。然而，对于移动的通信系统，它在理论上具有优良的特性，即在所有PSK方案中，它具有出色的误码率特性和最小的幅度波动。后一特征对于在其中必须使用非线性放大器的移动的终端中的使用是非常有吸引力的。为了在实际系统中使用TPSK方案，提出了一类新的卷积码。采用新卷积码的TPSK方案适用于传输二进制信号，并且在不扩展带宽的情况下改善了误码特性。
An important class of digital modulation is phase shift keying (PSK). 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 nonlinear amplifiers have to be used. A new class of convolutional codes is proposed in order to use the TPSK scheme in practical systems. The TPSK scheme with the new convolutional code is suitable for transmitting binary signals and it improves the error rate characteristics without bandwidth expansion.
