发明名称	APPARATUS AND METHOD FOR SYMBOL ERROR CORRECTABLE MODULATION AND DEMODULATION USING FREQUENCY SELECTIVE BASEBAND
摘要	Provided are a method and apparatus using a frequency selective baseband. Symbol-error correction modulation and demodulation is performed by generating a plurality of subgroups by dividing 2N spread codes or orthogonal codes used for frequency spreading into 2M (M<N) spread codes or orthogonal codes; selecting (P+L) subgroups; acquiring P spread codes by inputting M data bits to each of the selected P subgroups to select one spread code among the 2M spread codes of each subgroup; generating LM parity bits for symbol error correction using PM data bits inputted to the selected P subgroups; selecting one spread code among the 2M spread codes of the L subgroups by inputting the L*M parity bits to the L subgroups; and selecting the dominant values among the (P+L) spread codes acquired from the (P+L) subgroups to generate transmitting data including the dominant values, where N, M, P, and L are real numbers.
