A receiver circuit comprising first and second receivers for demodulating first and second parts, respectively, of a received signal. The receiver circuit also comprises an adjustment circuit for adjusting the demodulated signal from the first receiver. The output signal from the adjustment circuit is used as output signal from the receiver circuit which also comprises an adjustment value circuit for determining an adjustment value for the adjustment circuit in adjusting the output signal from the first receiver. The adjustment value circuit receives the demodulated signal from the second receiver and the output signal from the adjustment circuit and uses differences between these input signals for forming said adjustment value. The first receiver and the second receiver have different transfer functions within one and the same frequency range.

Receiver system comprising a main receiver and au auxiliary receiver for correcting imperfections in the main receiver

The present solution relates to a method in a first communication node () for suppressing noise in a communication system () utilizing an automatic gain control. The first communication node () receives () a signal from a second communication node (). Then, the first communication node () determines () if a gain level is changed. The signal gain is changed (). The next step is for the first communication node () to determine () if an inband interferer is present, and then to suppress () transient noise in the signal.
