WebThe most basic modulation method is called On–Off Keying (OOK). Just shut off the RF carrier if there is a zero to transmit, and send a full-power carrier if there is a one, and you have an OOK modulator. This is of course a form of amplitude modulation (AM), and it is used in many low-cost devices such as garage door openers. Web6.2 ON–OFF KEYING In OOK encoding, the optical light is pulsed on or off during each bit time, as shown in Figure 6.2 a. Each “1” bit is encoded into an optical pulse and each “0” bit is encoded into an off (no field) bit. Clearly, the maximum source bit rate is directly related to the rate at which the source can be switched on and off.

WebFor a turbulence variance σ21 of 0.003 and the transmitted optical power of −16.8 dBm, values for Q-factor are ∼11 and ∼8.5 for BPOLSK and NRZ-OOK schemes, respectively. The authors show that the predicted signal-to-noise ratio (SNR) for BPOLSK and NRZ-OOK schemes are ∼13.5 and ∼15 dB, respectively, for a BER of 10−6 and σ21 of 0.01.
