    Abstract: A variable frequency microwave pulse generator that includes a high voltage charger for charging with a high voltage, a high pressure gas tank for supplying insulation gas, and an electrode discharge unit. The electrode discharge unit includes a case, an accommodation section defined inside the case, and a pair of electrode sections disposed at one side and the other side of the accommodation section so as to face each other. The pair of electrode sections is spaced apart from each other to define a spark gap therebetween where the insulation gas supplied from the high pressure gas tank is loaded. An annular resonance recess is defined at the central portion of one electrode section of the pair of electrode sections, the depth of the resonance recess being variable in response to an adjustment knob disposed on the case being manipulated.

    Abstract: There is provided a method for acquiring and modifying uplink and downlink synchronization, by which, if there is a possibility of ISI occurring due to incorrect downlink synchronization of a terminal with a base station, the terminal receives a ranging response from the base station, modifies incorrect downlink synchronization, and acquires uplink synchronization in accordance with modified downlink synchronization. The method for acquiring and modifying uplink and downlink synchronization efficiently prevents, in a cooperative communication network, discrepancy in signal transmission synchronization between the base stations, excessive attenuation of a transmitted signal, or a delay caused by a difference in reflection paths.
