Title:
OPTIMAL METHOD FOR VISIBLE LIGHT COMMUNICATIONS
Document Type and Number:
WIPO Patent Application WO/2011/146520
Kind Code:
A3
Abstract:
As demand for wireless communications increases, it is becoming more important to efficiently use a frequency band. To support simultaneous multiple transmissions, a frequency band is divided into multiple channels or subbands. In this invention, a band division method for visible light communication (VLC) is invented with a goal of maximizing the communication efficiency of spectrum and fairness among channels. Reviewing the factors that should be considered when constructing channels in a visible light band, a new band division method using photo detection responsivity that yields the optimal and fair rate performance for the communication network is invented. Evaluation analysis shows the superiority of the invented scheme over currently existing band division method.
