Apparatus and method for interference mitigation and channel selection for visible light communication

摘要

A device and method for device association, interference mitigation and channel selection for use in a visible light communication (VLC) network. The method includes transmitting on every one of a plurality of supported color channels of a first device to estimate an ambient interference on each supported color channel. The method also includes receiving a transmission on at least some of the supported color channels, where the number of receiving color channels is less than or equal to the number of supported color channels of the transmitter. The method further includes calculating a channel quality index for each of the receiving color channels. The method still further includes selecting at least one of the receiving color channels of the first device to be used as a communication channel. The method also includes reporting the at least one communication channel to a second device in the VLC network. In certain embodiments, the method includes establishing guard color channels for each of the supported color channels.
