Abstract
A method of transmitting, by a transmitting device, an orthogonal frequency division multiplexing (OFDM) signal in a wireless communication system, the method including: generating, by a digital module of the transmitting device, a frequency-shifted OFDM baseband signal by performing frequency up-shift of a first signal by a difference between a carrier frequency fand a first frequency f, wherein the first frequency fis among frequencies corresponding to integer multiples of 128Δf closest to the carrier frequency f, and wherein Δf is an OFDM subcarrier spacing; up-converting, by an analog oscillator of the transmitting device, the frequency-shifted OFDM baseband signal by the first frequency fto generate an OFDM symbol signal at the carrier frequency f; and transmitting the OFDM symbol signal at the carrier frequency f.
