    • A mobile terminal has a simple construction in a mobile communication system of a small-zone system. The mobile terminal 1 transmits base station identification information transmitted from base stations 2a through 2d and information of the intensity of electric field of received radio wave from the base station to a position managing station, while the position managing station specifies the current position of the mobile terminal, based on the above-mentioned information by means of a relational expression of the intensity of electric field and a distance between a point of transmission and reception and a database of the base station. With the simple construction of the mobile terminal 1, the current position of the mobile terminal 1 can be specified with higher accuracy. Further, the mobile terminal 1 transmits the base station identification information of the plurality of base stations and the intensity of electric field of the received radio wave from the base station to the position managing station, the current position of the mobile terminal 1 can be specified with higher accuracy.

    • An asynchronous quadrature demodulator which comprises an asynchronous quadrature detector, a frequency compensating circuit for estimating and compensating a frequency offset between an oscillating frequency of a local oscillator of the asynchronous quadrature detector and a frequency of a received carrier frequency on the basis of correcting signals, a base band complex equalizer for eliminating a transmission-channel distortion due to a multiplex transmission and a data demodulator. Thereby, a reference carrier recovery circuit becomes unnecessary. Thus, the structure of the demodulator can be simplified. Further, the demodulator can stably operate on the transmission channel.
