APPARATUS AND METHOD FOR ALLOCATING FRACTIONAL RESOURCE IN VISIBLE LIGHT COMMUNICATION SYSTEM

摘要

PURPOSE: A fractional support allocating device and a method thereof are provided to support a multi user service as avoiding interference between multi users. CONSTITUTION: A photodiode information detecting unit(228) detects information of a photodiode which received the signal if the signal is received from at least one mobile terminal. A signal strength measuring unit(226) measures a strength of a signal received through the photodiode. A light source selecting unit(222) determines a light source area which will be allocated to at least one mobile terminal among the total light source area by suing a measuring result from the signal strength measuring unit and information from the photodiode detecting unit.
