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。

As the name of the new mode says, PSK (phase shift keying) modulates the carrier phase.

正如这种新操作模式的名字所指的，PSK(相移键控)调制载波的相位。

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。
