Web4 de set. de 2024 · Spread in Time On-Off Keying (TS-OOK) protocol was proposed as a technique to share the radio channel over the different terahertz nano-devices. TS-OOK is based on a Femtosecond-Long pulse modulation where communication data are sent using a sequence of pulses interleaved by a constant duration randomly selected. WebMost VLC systems are based on intensity modulation/direct detection scheme where the intensity of the optical carrier is modulated. In this paper, two types of modulation schemes namely On-Off Keying (OOK) and Phase Shift Keying (PSK) are investigated. First, the transmitter and receiver circuit for both types of modulation schemes are constructed.

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.
