Abstract: PURPOSE: A visible communication method is provided to guarantee a terminal mobility in a time division visible light communication system. CONSTITUTION: A terminal receives a cell border alarming information from a base station through a light source while performing a VLC(Visible Light Communication)(1413). The terminal receives the allocation of a new time slot. The terminal maintains the VLC through the new time slot and the previously allocated time slot(1421). If the reception of the cell border alarming information is discontinued, the terminal returns the previously allocated time slot. The terminal performs visible light communication through the new time slot.

Abstract: PURPOSE: An apparatus and a method for adjusting transmission power in a UWB communication system are provided to ensure the quality of a transmission signal. CONSTITUTION: If transmission power change request is received from at least one receiving node, an adaptive power adjustment unit(415) adjusts the length of a transmission pulse for each reception node to correspond to the transmission power value provided form the reception node. A wideband transmission antenna transmits a transmission signal to at least one reception node in the length of the transmission pulse adjusted for each reception node. A PPM(Pulse Position Modulation) modulator(405) performs the PPM for encoded data. A pulse generator(410) outputs the transmission signal by multiplying a transmission pulse by the output signal of the PPM modulator according to a selected time hopping code.

Abstract: A method for determining the gain factor of a photodetector in a visible light communication system and an apparatus therefor are provided to reduce the influence of surrounding light by determining the gains of each photodetector in consideration of the output values of each photodetector in a photodetector array. A plurality of photodiodes (500-1~500-n) convert the received light into an electric signal. A gain adjusting unit(520) determines the gain values of each output from each photodiode. A multiplier(510-1~510-n) multiplies and the gain values calculated in the gain adjusting unit by the output signal of a corresponding photodiode. A summer(530) adds up the output values of each photodiode to which the gain values calculated in each multiplier are reflected. A demodulator(540) demodulates the summed signal. A decoder(550) decodes the demodulated signal.
