摘要
Transmitting and receiving apparatuses for PAPR reduction and an adaptive PAPR control method thereof are provided. Prior to transmission, the transmitting apparatus limits the peak of a multi-carrier modulated signal using a mapping function that increases an output value with an input value and converges the output value to a predetermined value. The receiving apparatus receives the peak-limited signal, recovers the peak of the signal using a demapping function of the mapping function, and recovers data from the peak-recovered signal according to the multi-carrier modulation scheme used. According to the adaptive PAPR control method, a scaling factor can be set variably for the mapping function and the demapping function according to a sub-carrier modulation scheme.
