Abstract
A symbol mapping device includes a transmission data processing unit receiving two transmission data having the same length, and if the length is a first length, uses the two transmission data as two output data without change, and if the length is less than the first length, adds dummy data to the two transmission data to generate two output data, each data having the first length; a parity addition unit generating two parity-added transmission data based on the two output data, where the two parity-added transmission data each contain parity data added to the transmission data and each have a second length; a shuffle unit extracting two modulation data, being data to be mapped, from the two parity-added transmission data generated by the parity addition unit; and a mapping processing unit mapping the two modulation data to two time slots of constellation points.
