Radio device, radio device calibration system, calibration method, and calibration program

Abstract

The adaptive array wireless machine (1010) has an A / D converter (1200.1-1200.n) for receiving signals from the array antenna and then converting the analog signal into a digital signal, and for receiving signals from the A / D converter ( 1200.1~1200.n) for downsampling the output of the downsampling device (1210.1~1210.n) and an adaptive array processing part ( 1250). The least squares error signal is output from the adaptive array processing unit (1250) corresponding to the timing adjustment signal to the downsampling device (1210.1-1210.n). Accordingly, it is possible to accurately perform the calibration process of the transmission directivity of the adaptive array wireless device.

Description

technical field

[0001] The invention relates to a wireless device for adaptive array processing, a calibration system, a transmission directivity calibration method and a transmission directivity calibration program of the wireless device. Background technique

[0002] In recent years, in the rapidly developing mobile communication system (for example, personal portable mobile phone system: hereinafter referred to as PHS), in order to improve the frequency utilization efficiency of radio waves, it is proposed that multiple A PDMA (Path Division Multiple Access: Path Division Multiple Access) method in which a wireless mobile terminal device (hereinafter referred to as a terminal) and a wireless base station device (hereinafter referred to as a base station) of a user implements spatial multiple access.

[0003] This PDMA way adopts adaptive array technology. The so-called adaptive array processing is to calculate the weight vector composed of the reception coefficient (weig...
