Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 移動局との通信を継続しつつキャリブレ ーション処理を行うこと。 【解決手段】 受信無線回路104及び受信無線回路1 05は、それぞれ受信アンテナ102及び受信アンテナ 103を介して、移動局109からの無線通信信号及び CAL用CDMA無線信号送信手段110からのキャリ ブレーション用信号を受信して、受信した信号のダウン コンバートを行う。受信CDMA信号処理手段B(CA L用)107は、ダウンコンバートされたキャリブレー ション用信号を観測して各受信無線回路の特性誤差を測 定し、測定した特性誤差を記録手段108の補正テーブ ルに保存する。受信CDMA信号処理手段A(通信用) 106は、受信CDMA信号処理手段B(CAL用)1 07の観測動作と同時に、補正テーブルに保存された特 性誤差に基づいて、ダウンコンバートされた移動局10 9からの無線通信信号のCDMA復調処理を行う。 (57) [Problem] To perform a calibration process while continuing communication with a mobile station. SOLUTION: A reception radio circuit 104 and a reception radio circuit 1 are provided. 05 receives a radio communication signal from the mobile station 109 and a calibration signal from the CDMA CDMA radio signal transmitting means 110 via the receiving antenna 102 and the receiving antenna 103, respectively, and downconverts the received signal. Do. Receive CDMA signal processing means B (CA L) 107 observes the down-converted calibration signal, measures the characteristic error of each receiving radio circuit, and stores the measured characteristic error in the correction table of the recording unit 108. Receive CDMA signal processing means A (for communication) 106 is a reception CDMA signal processing means B (for CAL) 1 07, the mobile station 10 down-converted based on the characteristic error stored in the correction table at the same time. 9 for CDMA demodulation of the wireless communication signal.
