APPARATUS FOR PROCESSING RECEIVED SIGNAL, METHOD THEREOF, AND METHOD FOR SELECTING MAPPING RULE

摘要

An apparatus for processing a received signal, method thereof, and mapping rule selecting method are disclosed, by which radio communications can be smoothly carried out in a receiving terminal (200) receiving signals via at least two antennas (201a) in a manner of estimating data accurately. The present invention includes performing transmission according to an adaptively decided mapping rule and demapping on a symbol signal received via the plurality of antennas (201a), extracting reliability information for bit signal obtained from the demapping, and re-performing the demapping on the symbol signal received via the plurality of antennas (201 a) using the reliability information.
