摘要： Provided are a flexible and transparent carbon nano tube (CNT) thin film transistor using a degradable polymer substrate, and a display adapting the CNT thin film transistor. The polymer substrate is formed of a polymer material that is naturally degraded, and a CNT channel, where a semiconductive CNT is dispersed on a transparent organic material, is prepared on the polymer substrate. Source and drain electrodes, where a conductive CNT is ejected on a transparent organic material, are connected to both sides of the CNT channel. A gate, where a conductive CNT is dispersed on a transparent organic material, is disposed on or below the CNT channel, and a gate insulation layer including a transparent organic material is disposed between the CNT channel and the gate.

摘要： Disclosed herein is a portable Internet analyzer (PIA) having a handover test function. The portable Internet analyzer includes a transmission unit, a reception unit, a switching unit, and a central control unit. The transmission unit encodes the various DownLink signals of a serving and/or target Base Station (stBS) using a preamble index, synthesizes the encoded signals, and sends the synthesized signals to a Portable Subscriber Station (PSS). The reception unit receives various UpLink (UL) signals from the PSS, and decodes the UL signals using the cell Parameters of the stBS. The switching unit selectively switches the transmission unit and the reception unit to the PSS. The central control unit generates various Media Access Control (MAC) messages to be sent to the PSS through the transmission unit in association with the handover test, analyzes handover test-related MAC messages received through the reception unit, and controls switching operation of the switching unit.

摘要： Disclosed herein is a method of acquiring Uplink (UL) synchronization for a mobile WiMax system analyzer. When a DL sub-frame is received, the method is performed on a Portable Subscriber Station (PSS) having a test mode function of creating a UL sub-frame through the mobile WiMax system analyzer having signal generating means configured to store the CID information in advance and signal analyzing means configured to receive and analyze the DL sub-frame.

摘要： Disclosed herein is a time synchronizing apparatus for a mobile WiMAX analyzer. The time synchronizing apparatus includes a Global Positioning System (GPS) receiver and a synchronization control unit. The GPS receiver outputs a GPS signal that is synchronized with the GPS time using information received from a GPS satellite. The synchronization control unit compares the GPS signal and a reference signal, which is generated using an internal clock, and controls synchronization according to the result of the comparison. The synchronization control unit includes an oscillator, a divider, an offset comparison unit and a processor. The oscillator outputs an oscillation signal having a predetermined frequency. The divider divides the oscillation signal into the reference signal. The offset comparison unit compares the differences between the GPS signal and the reference signal, and outputs the result value of the comparison. The processor controls the oscillation frequency of the oscillator until the result value satisfies a predetermined reference value.
