Abstract:
    The invention is used to solve the problem of which the DC bias can not be simply and accurately removed from the signal processor in the receiver. It comprises the following steps: the control module supervises the state of each time slot in the logic channel, informs the idle time slot to the calculation module and disconnects the receiving signal of the signal processor in the idle time slot; according to the sampling signal outputted from the signal processor in the idle time slot, the calculation module calculates the DC bias value of the signal processor and outputs the result to the bias removing module; according to said DC bias value, the bias removing module removes the DC bias of the sampling signals from the signal processor.
