Performance Improvement in Li-Fi based Network: DE - Softcover

Inhaltsangabe

Light Fidelity (Li-Fi) is an Optical wireless communication (OWC) technology, which uses light from light emitting diodes (LEDs) as a medium to deliver network, mobile, high-speed communication in a similar manner to Wi-Fi. Li-Fi can be simply position to remain Wi-Fi but in its place of radio waves light is used as a medium.Now, data is transmitting using light whose amount varies faster than human eye to capture. In its place of using modems, Li-Fi uses LED bulbs with transceiver. Data transmission in Li-Fi is about 100 times faster than Wi-Fi. OFDM stands and 4QAM,16 QAM ,32QAM,64QAM has been reported. BER v/s SNR curves are simulated to improve their performance using light fidelity network.There are OFDM modulation technique using image transmit to transmission to receiver using QPSK and QAM or 4QAM, 16QAM, 32QAM, 64QAM using light fidelity network are improve their performance.
