摘要： A visible light receiver and method for a visible light communication system. A PD array converts a received optical signal to an electrical signal, a position controller outputs a control signal to adjust the position of the PD array according to values of signals output from PDs of the PD array, so that a highest output is from a predetermined area of the PD array A driving motor adjusts the position of the PD array according to the control signal received from the position controller, and a summer sums the values of the signals received from the PDs. A demodulator demodulates the output from the summer, and a decoder decodes the output of the demodulator.
