CALIBRATION OF COMMUNICATION APPARATUS

A communication apparatus (200) has a calibration mode in which a signal is passed through circuitry (30, 80) of the apparatus, and a controller (160) measures the response of the circuitry (30, 80) to the signal and adjusts the circuitry (30, 80) to improve performance. The signal used for calibrat...

Summary:A communication apparatus (200) has a calibration mode in which a signal is passed through circuitry (30, 80) of the apparatus, and a controller (160) measures the response of the circuitry (30, 80) to the signal and adjusts the circuitry (30, 80) to improve performance. The signal used for calibration has a wider bandwidth than the bandwidth of signals used for transmission. The wider bandwidth may be provided by reconfiguring a digital filter (20) from low-pass to high-pass.
