The visible-light communication utilizing the white LEDs is a kind of optical wireless communication characterized by high emission power rate,spreading everywhere,electromagnet free interference and energy-saving,etc.

As a potential technology for high-speed indoor wireless networks,visible-light communication still needs to overcome the penalties of background-light noise and the multipath effect.

The current situation and development trend of indoor visible light communication by white LED illumination

The visible light communication(VLC) is a kind of optical wireless communication that uses the white LEDs.

Thanks to the white LED s excellent properties such as low power consumption, long lifetime, high reliability and short response time, it is possible to upgrade the indoor white LED illumination source to a wireless optical communication system In this thesis, we analysised the current visible light communication system and discussed the key t.
