Abstract: PURPOSE: An optimum power point tracker and a system for controlling the same are provided to improve generation efficiency by preventing power loss of the system due to the non-uniform output of solar cells. CONSTITUTION: Orthogonal perturbation source(103) supplies orthogonal perturbation signals with the orthogonality. Electric power converters(102, 105, 108) control the output power from energy sources in response to control variables. An output coupler(110) couples the output power from the electric power converters. A perturbation power observer(111) measures the coupled orthogonal perturbation power corresponding to each orthogonal perturbation sources from the coupled output power. A cross correlation array(112) implements cross-correlation between the orthogonal perturbation signals.

Abstract: A media access control method in an optical wireless network and an apparatus therefor are provided to reduce maintenance costs by simplifying installation and operation of an optical network. A hybrid MAC module(210) processes uplink messages transferred as radio signals from CPEs(Customer Premise Equipments)(300_1-300_M), and processes a downlink message transferred as a light signal from an OLT(Optical Line Termination)(100). An optical radio physical layer module(220) converts the uplink messages processed by the hybrid MAC module into light signals and outputs the same, and converts the downlink message processed by the hybrid MAC module into radio signals and outputs the same. A light signal transmission/reception module(230) transmits/receives the light signal between the optical radio physical layer module and the OLT. A radio transmission/reception module(240) transmits/receives the radio signals between the optical radio physical layer module and the CPEs.
