RECEIVER AND RECEPTION METHOD FOR LAYERED MODULATION

摘要

PURPOSE: A receiving device and method for hierarchical modulation is provided to decode higher layer information based on lower layer decoding information, thereby reducing interference between layers. CONSTITUTION: A phase compensation part(210) transfers a phase compensated signal to a basic layer decoding part(230) by compensating the phase of a received signal. The basic layer decoding part decodes an information bit of the basic layer among several layers. The basic layer decoding part calculates a bit metric including code bit information of the basic layer based on the phase compensated signal. An enhancement layer decoding part(250) successively decodes an information bit of the enhancement layer which is a higher layer of the basic layer based on a decoding result of a lower layer.
