Abstract: PURPOSE: A base station system using the receiver of a GPS(Global Positioning System) is to provide the best service at the minimum cost by installing only a GPS antenna and a remote GPS receiver. CONSTITUTION: A GPS(200) antenna receives the GPS signal received from a satellite. A remote GPS receiver(220) is composed of a receiving part(222) and a base station interface part(224) demodulating the receiving signal from the GPS(200) antenna, converting it into a signal necessary for a base station system(260), and transmitting the signal to the base station system(260). A GPS clock distribution part(255) located at the base station system(260) receives a signal to be transmitted at the remote GPS receiver(220), and distributes the signal inside of the base station system(260).

Abstract: PURPOSE: An apparatus for estimating inductance of a permanent magnet synchronous motor and a method therefor are provided to estimate inductance in real time regardless of angle estimation errors. CONSTITUTION: An inductance estimator injects a signal having a frequency different form an operation frequency into the driving signal of a permanent magnet synchronous motor(1000). The inductance estimator varies an inductance value used for the control of the permanent magnet synchronous motor(1001). The inductance estimator senses a current response(1002). The inductance estimator stores and determines the size of detected current response(1003). The inductance estimator determines whether the detected current response number is plural or not(1004). The inductance estimator compares the size of a plurality of current responses(1005). The inductance value used for the control of the permanent magnet synchronous motor is determined(1006). The inductance estimator determines the determined inductance value as the real inductance value of the permanent magnet synchronous motor(1007).

Abstract: PURPOSE: An optical fiber matching system is provided to connect a main unit of a pico-BTS(Base Transceiver Station) to a PRU(Pico-BTS Radio Unit) and a repeater by using an optical fiber cable so that it can overcome a limit of a distance between the main unit and the PRU. CONSTITUTION: An optical fiber matching system comprises a main unit(100), a radio unit(200) and an optical fiber cable(101). The main unit(100) performs an optical fiber conversion by a frequency modulation on a radio frequency signal generated from a pico-BTS, and demodulates the optically converted signals by an electric conversion. The radio unit(200) also performs an optical fiber conversion by a frequency modulation on a radio frequency signal generated from the pico-BTS, and demodulates the optically converted signals by an electric conversion. The optical fiber cable(101) transmits the frequency modulated optical signals between the main unit(100) and the radio unit(200).
