The ultra wideband (UWB) radio models have been introduced with pulse-position-modulation (PPM), on-off-keying (OOK) and pulse-amplitude-modulation (PAM).
分析了超宽带冲激无线电的脉位调制、通断键控调制和脉冲幅度调制的信号模型。

We also realize wavelength remodulation for carrying upstream on-offkeying (OOK) data to reduce the cost budget at the optical network unit.
为了降低光网络单元的成本预算，我们对下行的光载波进行了上行传输开关键控信号的重调制。

Chaotic on-offkeying (COOK) and differential chaos-shift keying (DCSK) are two simple modulation schemes.
