Compared to current phase shift keying (PSK) modulation by a code, there is a further modulation by a sub-carrier.

与当前通过编码的相移键控(PSK)调制相对，还存在另外的通过子载波的调制。

Digital mod technology in the digital communication occupies a very important position, commonly used digital modulation are: frequency shift keying (FSK) and phase-shift keying (PSK), and so on.

数字调制解调技术在数字通信中占有非常重要的地位，常用的数字调制有：移频键控(FSK)和移相键控(PS K)等。

The first segment 310 of the TPS data block (bit so) is an initialization bit for a differential binary phase shift keying (2-PSK) modulation.

TPS数据块的第一段310（比特S0）为差分二进制相移键控调变的初始比特。
