QPSK Quaternary Phase Shift Keying

用法例句

The quadrature phase-shift keying(QPSK)modulation technique has widespread application in engineering.

正交相移键控(QPSK)调制技术已经在工程中得到了广泛应用,然而随着电子对抗技术的发展,QPSK的非平衡调制技术水平也得到了相应的提高,以专门针对通信或定位中的QPSK调制进行干扰。

And an all-optical regenerator design scheme for quadrature phase-shift keying(QPSK) and differential quadrature phase-shift keying(DQPSK) signals was investigated through numerical simulations.

对适用于正交相移键控和差分正交相移键控信号的全光再生器进行了仿真。
