A RECEIVER DEVICE WITH ADAPTIVE IQ CORRECTION

摘要

A receiver device (100) arranged to receive an input signal, and comprising a first (105) and a second (110) receiver. The first (105) and second (110) receivers are arranged to receive and demodulate to baseband level respective first (A) and second (B) parts of the input signal, and the receiver device (100) also comprises an adaptive IQ correction component (120) arranged to receive the output baseband signal from the first and second receivers, and to correct IQ errors in the output baseband signal from the first receiver by means of the received output baseband signals. The first (105) and second (110) receiver are arranged to have different transfer functions within one and the same frequency range, and the corrected output baseband signal from the first receiver is arranged to be the output signal from the receiver device (100).
