Abstract
The present invention relates to a wireless communication system and, particularly, to a method and an apparatus therefor, the method comprising the steps of: inputting, into an artificial neural network, (1) a data modulation symbol, (2) information for generating a reference signal sequence, and (3) PAPR margin information, so as to output a complex sequence from the artificial neural network in a frequency domain; generating an OFDM symbol by applying the inverse Fourier transform to the complex sequence; and transmitting the OFDM symbol.
