Radio communication apparatus in CDMA communication system with calibration |
摘要 |
In a CDMA radio communication system including a plurality of transmit radio sections, calibration signals with a bandwidth equivalent to that of spread spectrum signals used for communications are generated in base band processing sections. These calibration signals are input to transmit radio sections that convert the spread spectrum base band signals to radio signals. Then, the characteristics of the transmit radio sections are detected from the calibration signals that have passed through the transmit radio sections. <IMAGE> |
