摘要: As the number of internet users continues to increase, demand for more wireless frequency spectrum has grown significantly over years. Given limitations in Wireless Fidelity (WiFi) networks, it becomes evident that current allocation schemes cannot meet needs increasing higher data rate devices. Visible Light Communication (VLC) emerged as one promising technologies address crunch and other anomalies associated with WiFi networks. VLC provide high-speed, secure reliable communication using Emitting Diode (LED). This paper reviews various modulation suitable Furthermore, performance analysis these terms normalized power requirement, Signal Noise Ratio (SNR), spectral efficiency, dimming factor Bit Error Rate (BER) are discussed. Finally, applications presented.
