Web6.2 ON–OFF KEYING. In OOK encoding, the optical light is pulsed on or off during each bit time, as shown in Figure 6.2a. 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. Web1 de nov. de 2024 · Backscatter communication holds potential for ubiquitous and low-cost connectivity among low-power IoT devices.
