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.

调频差分混沌键控(FM - DCSK)的比特能量是常数，可以提高传输速率，但和CS K相比较，性能上仍有差距。

The energy per bit of FM-DCSK is kept constant to increase the transmission rate. But the performance of CSK is yet better than that of FM-DCSK.
