混沌开关键控(COOK)和差分混沌键控(DCSK)是两种基本的调制方案。

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

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。

We also realize wavelength remodulation for carrying upstream on-off keying (OOK) data to reduce the cost budget at the optical network unit.
