    摘要: Disclosed is a method and system by which a base station without a Global Positioning System (GPS) receiver acquires time synchronization in a Broadband Wireless Access (BWA) communication system. The method includes scanning neighbor base stations around a first base station and requesting time synchronization information from the scanned neighbor base stations by the first base station; receiving responses from predetermined neighbor base stations having already acquired time synchronization from among the neighbor base stations, the responses including time synchronization information of the predetermined neighbor base stations; and selecting a second base station from among the predetermined neighbor base stations and acquiring time synchronization based on the time synchronization information of the second base station.

    摘要: In an energy recovery circuit of a PDP, after storing energy in the inductor, the panel capacitor is charged by using a resonance between the inductor and the panel capacitor and the stored energy. At that time, a voltage greater than a voltage Vs/2 is stored in an energy recovery capacitor. Then, the panel capacitor can be charged to Vs even when a parasitic component exists in the energy recovery circuit. In addition, the energy remaining in the inductor can be used in a discharge. Also, the charging time of the panel capacitor is shorter than the discharging time of the panel capacitor to allow stable discharge.
