Abstract
An apparatus for receiving signals includes a receiver for receiving a time domain signal from a transmitter, wherein at least one first information bit is mapped, resulting in at least one first mapped symbol; at least one second information bit is mapped, resulting in at least one second mapped symbol; the at least one second mapped symbol is multiplied by at least one third information bit; and the time domain signal is generated from the at least one first mapped symbol and the at least one second mapped symbol.

A method of transmitting signals to a receiver by a transmitter, the method comprising:
- modulating at least one first information bit using a first constellation mapping, resulting in at least one first modulated symbol;
- modulating at least one second information bit using a second constellation mapping, resulting in at least one second modulated symbol;
- modulating at least one third information bit using a third constellation mapping, resulting in at least one third modulated symbol,
- wherein the at least one second modulated symbol, which is a result of the modulation of the at least one second information bit, is combined with the at least one third modulated symbol, which is a result of the modulation of the at least one third information bit;
- transforming the at least one first modulated symbol which is not combined with the at least one third modulated symbol and the at least one second modulated symbol which is combined with the at least one third modulated symbol into a time domain signal,
- wherein the at least one first modulated symbol is located before the at least one second modulated symbol in a time domain;
- inserting a cyclic prefix into the time domain signal;
- and
- transmitting the time domain signal into which the cyclic prefix is inserted.
