Apparatus and method for transmitting data using a plurality of carriers
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.
1. A method of transmitting signals to a receiver, the method comprising:
transforming a first signal and a second signal to a time domain signal; and
transmitting the time domain signal to the receiver,
wherein:
the first signal is modulated, resulting in at least one first modulated symbol,
the second signal is modulated, resulting in at least one second modulated symbol,
a third signal including information for Peak to Average Power Ratio (PAPR) reduction is applied to the at least one second modulated symbol, which is a result of the modulation of the second signal,
the third signal including information for PAPR reduction is not applied to the at least one first modulated symbol, which is a result of the modulation of the first signal, and
the at least one first modulated symbol is located before the at least one second modulated symbol.
2. The method of claim 1 , wherein the first signal is a pilot signal.
3. The method of claim 1 , wherein the second signal is a data signal.
4. The method of claim 1 , wherein the PAPR reduction is carried out by controlling a phase of the at least one second modulated symbol based on the information for PAPR reduction.
5. An apparatus for transmitting signals to a receiver, the apparatus comprising:
a transmitter configured to transform a first signal and a second signal to a time domain signal and to transmit the time domain signal to the receiver,
wherein:
the first signal is modulated, resulting in at least one first modulated symbol,
the second signal is modulated, resulting in at least one second modulated symbol,
a third signal including information for Peak to Average Power Ratio (PAPR) reduction is applied to the at least one second modulated symbol, which is a result of the modulation of the second signal,
the third signal including information for PAPR reduction is not applied to the at least one first modulated symbol, which is a result of the modulation of the first signal, and
the at least one first modulated symbol is located before the at least one second modulated symbol.
6. The apparatus of claim 5 , wherein the first signal is a pilot signal.
7. The apparatus of claim 5 , wherein the second signal is a data signal.
8. The apparatus of claim 5 , wherein the PAPR reduction is carried out by controlling a phase of the at least one second modulated symbol based on the information for PAPR reduction.
