1. A receiver comprising:
one or more receiving antennas configured to receive a plurality of bitstreams transmitted from one or more transmission antennas;
a bitstream candidate estimator configured to estimate a prescribed number of bitstream candidates among possible combinations of the received bitstreams and to calculate reliability information for each of the candidates;
a bit-based estimator configured to produce a bit-based estimation result for each bit of the transmitted bitstreams based on the estimated candidates and the associated reliability information, the bit-based estimation result being adjusted by an adjusting criterion determined by the reliability information; and
a decoder configured to decode the transmitted bitstreams based on the adjusted bit-based estimation result.
