| 摘要 |
The present invention relates to a receiver (10) for receiving a digitally modulated signal. The receiver (10) is arranged to estimate a received analogue signal (S in), wherein the receiver (10) comprises a Low Noise Amplifier (11), LNA, arranged to amplify the received analogue signal (S in). The receiver is particularly characterized in that it further comprises a non-linear error detector (17); the amplified signal (S amp) being arranged to be input into the detector (17). The non-linear error detector is arranged to detect and output an estimation of the linearizer tuning parameters (19), said parameters indicating non-linear errors in the amplified signal (S amp). The receiver (10) further comprises a linearizer (13) being arranged to linearize the amplified signal (S amp) on the basis of the output linearizer tuning parameters (19). The present invention also relates to a corresponding method.
