Abstract

An apparatus for transmitting/receiving a signal and a method of transmitting/receiving a signal are disclosed. In particular, an apparatus for transmitting/receiving a signal and a method of transmitting/receiving a signal, which are capable of increasing a data transfer rate, are disclosed. Symbols are mapped according to a plurality of symbol mapping methods such that gaps between neighboring symbols are identical. The mapped symbol data is modulated and transmitted. Accordingly, it is possible to improve a data transfer rate on the basis of a SNR gain and improve signal transmission/reception performance of a transmitting/receiving system. If a multi-mapping method or a multi-coding method is used, a relationship between a necessary SNR and a transfer rate is adjusted so as to improve transmission efficiency.
