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. http://cje.ustb.edu.cn/article/doi/10.13374/j.issn2095-9389.2024.12.14.001

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. Web18 de dez. de 2024 · The requirement on very low power consumption means that the power is reduced to about 1% of the PCR. To allow for a power efficient receiver implementation, the data is sent using ON-OFF keying (OOK). A simple receiver architecture suitable for decoding OOK may be based on an envelope detector.

Web18 de fev. de 2024 · On off keying (OOK) scheme is known as the simplest form of amplitude-shift keying modulation by using two statuses: ON/OFF to transmit data. In the simplest form of OOK, a binary one is presented by a carrier for a specific duration and a binary zero is presented by the absence of a carrier for the same duration.
