Abstract
A transmitting system, a receiving system, a transmitting method and a receiving method capable of implementing communications with multiple rates are described. The transmitting system comprises: a transmitting-side selection apparatus for selectively inputting input bit data to one of a first constellation mapping modulation apparatus and a second constellation mapping modulation apparatus based on a rate to be transmitted; the first constellation mapping modulation apparatus for performing a first constellation mapping modulation on the signal input thereto based on a selection made by the transmitting-side selection apparatus, so as to obtain a constellation-mapped signal; the second constellation mapping modulation apparatus for performing a second constellation mapping modulation on the signal input thereto based on the selection made by the transmitting-side selection apparatus, so as to obtain a constellation-mapped signal; and an OFDM modulation apparatus for performing an OFDM modulation on the constellation-mapped signal to obtain an OFDM-modulated signal for transmission.
