Transmitting apparatus and transmitting method
Abstract
A duplicating section duplicates a bit sequence to be input, and a 16QAM section modulates a bit sequence of a duplicating source to form a symbol, a 16QAM section modulates the duplicated bit sequence to form a symbol, an S/P section parallel converts the symbol sequence input in series, an S/P section parallel converts the symbol sequence input in series, and an IFFT section provides IFFT processing to the input symbol sequence. Since each of multiple same bits duplicated by the duplicating section is included in a different symbol, each of the multiple same bits is allocated to each of multiple subcarriers each having a different frequency by IFFT processing. As a result, a multicarrier signal including the multiple same bits each having a different frequency is generated.
