摘要:
Disclosed is a method for processing incoming signals of photo-detectors in a visible light communication system. The method includes: dividing symbol duration into divided durations according to an equal time interval to set the divided durations to a plurality of time slots, the symbol duration being a time required to transmit one of a symbol and a bit; receiving visible light signals through a photodiode array in a receiver; determining a gain value of each of the photodiodes during a time slot, in consideration of each photodiode area on the photodiode array during the time slot and the time slot position within the symbol duration; multiplying a gain value of each of the photodiodes by an output value of a corresponding photodiode; and summing up output values of each of the photodiodes by which the gain value has been multiplied and calculating a total of output values of the time slot.
