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. Web10 de abr. de 2024 · 1. ASK(Amplitude Shift Keying)称为幅移键控，通常指二进制幅移键控2ASK，只对载波作幅度调制。当2ASK的调制深度为100%时，只有比特“1”有信号，比特“0”没有信号，所以称为On-Off Keying，简称为OOK调制。OOK调制是一种特殊的ASK调制，调制后的波形为射频脉冲信号。 2.

6.2 ON–OFF KEYING - Optical Communications, 2nd Edition …

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. WebVLC uses On-Off Keying (OOK) and Pulse Position Modulation (PPM). But recently, a noticeable increase in the use of a number of other modulation techniques such as Digital Pulse Interval Modulation (DPIM) and Dual-header Pulse Interval Modulation (DH-PIM) to improve the efficiency in terms of both the bandwidth and power has been observed. nordstrom rack powell st https://nakytech.com
