ABSTRACT:
A method for estimating and removing a time varying DC-offset includes the steps of dividing the received burst into blocks (902), then finding the maximum and minimum values in each block (904). Once the maximums and minimum values have been found, the upper and lower envelopes are determined (906). The DC-offset path is then calculated by taking the average of the upper and lower envelope (908). Once determined, the DC-offset path information is used in order to subtract the DC-offset from the desired signal.
