摘要： In a calibration apparatus, which calibrates the phases of main signals input to each of the antenna elements of an array antenna, a calibration signal generation portion generates calibration signals, which are combined with main signals. An RF switch alternately inputs to a wireless receiving portion the signals radiated from other antenna elements via a first antenna element, and the signals radiated from other antenna elements via a second antenna element, and causes demodulation. The calibration detection portion detects calibration signals from the demodulated signals, and the weight generation portion uses the detected calibration signals to calculate calibration weights, which are set in the phase shifter, to control the phases of main signals for input to each antenna element.

摘要： The present invention relates to a calibration apparatus for an array antenna having a plurality of antenna elements. The calibration apparatus comprises a conversion unit detecting a calibration signal from an output of a transmission unit to convert the detected calibration signal into a predetermined reception radio frequency and outputting the converted calibration signal together with a reception main signal to a reception unit, a detecting unit detecting the calibration signal from an output of the reception unit for each of the antenna elements to obtain a relative phase difference between the calibration signals, and a phase correcting unit correcting a phase difference with respect to one of or both a transmission main signal and a reception main signal based on the obtained relative phase difference. This configuration can eliminate the need for a radio transmitter-receiver dedicated to a calibration signal, thus facilitating the calibrations.

摘要： By applying a modification considering a frequency difference to a phase error signal, phase lock is established in a short period of time even when there is a frequency difference. A jump detector detects a discontinuous jump of the phase error signal which occurs when there is a frequency difference, and a state transition is caused in a state storage device in accordance with the resulting detection signal. A holding device corrects the phase error signal in accordance with the state stored in the state storage device and outputs the thus corrected phase error signal as a frequency-phase error signal.

摘要： A communication system includes a mobile station and a base station. The mobile station calculates estimated TA information based on the position of the mobile station and an amount of propagation path delay. The mobile station determines, based on TA information transmitted from the base station and the estimated TA information, whether the TA information is addressed thereto. The mobile station determines whether to transmit “Message 3” to the base station depending on determination results, and transmits “Message 3” when the TA information is addressed thereto.
