Abstract:
A demodulation apparatus includes: a synchronization detector to extract a reception mapping point from a reception signal transmitted wirelessly and modulated by a modulation scheme associating discrete values with the mapping points on a complex plane; a reception mapping point corrector to correct the extracted reception mapping points and to output post-correction mapping points; a hard-decision determiner to determine that a reference mapping point having a minimum error with the post-correction mapping point is a reference mapping point to be outputted as a demodulation result based on the inputted error vectors; a reference mapping point estimator to update the reference mapping point to be outputted as the demodulation result using the post-correction mapping points; and a correction coefficient updater to update the correction coefficient using the error between the reference mapping point to be outputted as demodulation result and the post-correction mapping point.

Claim (Index 10):
The demodulation apparatus according to  claim 3 , further comprising:\n an orthogonality error detector to detect orthogonality error of the reference mapping points; and an orthogonality error corrector to correct the reception mapping points or the post-correction mapping point such that the orthogonality error approaches zero.
