Abstract. Recent mobile communication standards, such as LTE, Wi-Fi, DVB-T, WiMAX, are based on orthogonal frequency division multiplexing (OFDM). This is due to the fact that OFDM signals allow the efficient use of frequency band in conditions of multipath fading. The aim of this paper is to develop a method for estimating the parameters of OFDM signals, namely: the number of orthogonal channels (subcarriers) and sampling rates for modulation/demodulation. The model of these signals is presented, taking into account the features of their formation and application. The analysis of the model showed regular relationships between the parameters of OFDM signals and the parameters of signal formation. The revealed regular relationships are based on the features of the autocorrelation function shape and the features of the spectrum of OFMD signals. The correctness of the theoretical provisions is confirmed by checking the operability of the proposed method on real signals.
Keywords: OFDM-signals, modulation, signalization parameters.
