Abstract
A method for an apparatus comprises obtaining a frequency modulation parameter corresponding to a frequency change rate of a frequency-modulated subcarrier; generating an Orthogonal Frequency Division Multiplexing (OFDM)-based waveform signal comprising a plurality of frequency-modulated subcarriers, the plurality of frequency-modulated subcarriers modulated according to the obtained frequency modulation parameter; and outputting the OFDM-based waveform signal. A plurality of modulated symbols may be generated from a sequence of bits and the modulated symbols may be precoded, according to the frequency modulation parameter, to generate precoded symbols. The OFDM-based waveform signal may then be generated from the precoded symbols. A corresponding method for detecting and decoding the waveform signal is also provided.
