COMMUNICATION APPARATUS FOR QUALITY OF SERVICE IN VLC SYSTEM IN WHICH LED TRANSMISSION EFFICIENCY IS CHANGED AND METHOD THEREOF

摘要

Disclosed are a communication apparatus for QoS in a VLC system in which LED transmission efficiency is changed and a method thereof. The apparatus includes: a signal generating unit for generating a transmission signal including pilot and preamble symbols in each transmission unit; a digital information encoding unit for preventing performance degradation due to a channel; a multiplexer for multiplexing the encoded information; and a modulator for modulating the multiplexed information. Accordingly, the present invention can provide a service satisfying the QoS through application to an LED-ID system field.;COPYRIGHT KIPO 2017
