What is OFDM demodulation?

OFDM Demodulation

An OFDM demodulator demultiplexes a multi-subcarrier time-domain signal using orthogonal frequency division multiplexing. OFDM demodulation uses an FFT operation that results in N parallel data streams.

How to generate OFDM signal in Matlab?

waveform = hMod( insignal ) applies OFDM modulation the specified baseband signal and returns the modulated OFDM baseband signal. waveform = hMod( data , pilot ) assigns the pilot signal, pilot , into the frequency subcarriers specified by the PilotCarrierIndices property value of the hMod system object.
