DIVERSITY COMBINING METHOD AND DIVERSITY RECEIVER APPARATUS

摘要

In a diversity receiving apparatus for demodulating a plurality of signals received with a plurality of antennas and performing signal demodulation using the demodulated signals of the same number as that of the antennas, first combiner combines the plurality of received signals once, and hard detecting unit makes a hard detection of the combined result to thus compute a plausible code point. Propagation path re-estimators compute propagation path characteristics of high estimating accuracy by using this plausible code point, and divide the demodulated signals of the same number as the antennas by the obtained propagation path characteristics. Second combiner again combines the results to thereby achieve a highly reliable result of demodulation.
