Abstract. The article discusses the features and main stages of the formation of OFDM signals. Analytical models of signals with orthogonal frequency multiplexing in the time and frequency domains are presented in the absence and presence of a mismatch in the carrier frequency of the transmitter and receiver. The analysis of the models allowed us to identify the parameters that affect the frequency and phase spectrum of signals. The study was carried out and the dependences of the reception quality of OFDM signals (the ratio of signal power to the power of equivalent noise) on the normalized error of the carrier frequency estimation were obtained.
Key words: OFDM-modulation, carrier frequency, orthogonal subcarriers, frequency mismatch, signal fading.
