On–off keying (OOK) denotes the simplest form of amplitude-shift keying (ASK) modulation that represents digital data as the presence or absence of a carrier wave. In its simplest form, the presence of a carrier for a specific duration represents a binary one, while its absence for the same duration represents a binary zero. Some more sophisticated schemes vary these durations to conve… Web1 de jun. de 2024 · A UWOC system based on acousto-optic modulator and NRZ-OOK modulation is verified. • The highest data rate of 15 Mbps with 9 m distance and 1.53 × 10-4 BER is obtained..
