Dynamic DC offset canceling apparatus and dynamic DC offset canceling method

摘要

The dynamic DC offset canceling apparatus includes: section 104 that detects dynamic DC offset in longest overlapping part sequences from the differences between the sampling values of a first longest overlapping part sequence and the sampling values of a second longest overlapping part sequence, the first longest overlapping part sequence and the second longest overlapping part sequence being overlapping part sequences in a training sequence of the received signal; section 105 that detects dynamic DC offset outside the longest overlapping part sequences from the difference between an average value of sampling values of a received signal which exists in a burst before the first longest overlapping part sequence, and an average value of sampling values of a received signal which exists in a burst after the second longest overlapping part sequence; and section 106 that adaptively subtracts a DC offset value from the received signal based on these results.
