The present invention relates to a polar coordinate modulation apparatus and a polar coordinate modulation method. The polar coordinate modulation apparatus comprises: a quadrature amplitude modulation mapping unit for generating symbols having the same Euclidean distance; and a constellation rearranging unit for rearranging a constellation of the symbols generated from the quadrature amplitude modulation mapping unit, wherein the symbols of the constellation rearranged by the constellation rearranging unit are modulated by separating size and phase information. The modulation method comprises the steps of: mapping data to symbols by quadrature amplitude modulation (QAM); rearranging a constellation of the mapped symbols; and separating size and phase information in the rearranged symbols.
