ABSTRACT:
A device for processing an intermediate analogue signal received from a previous system with a baseband processor. The processor includes an ordinary feedback loop for adjusting the strength of the intermediate analogue signal received from the previous system. The processor further includes a first DC offset reduction loop and a second DC offset reduction loop. A programmable filter bank and the corresponding control elements are provided so that the second DC offset reduction loop can reduce the DC offset in a flexible way. In the present invention, the DC offset can be reduced effectively and the gain training period relating to the previous system and the baseband processor can be shortened.
