Re: Regarding ofdm modulator and demodulator block

[Marcus Müller]

We still have the OFDM framework in GNU Radio 3.7, 3.8 and what will be 
3.9; You'll find examples in the gr-digital examples folder! (typically, 
/usr/share/gnuradio/examples/digital or somewhere similar)

Also, don't forget that *generating* an OFDM signal is really, really 
simple with the FFT block, stream to vector, vector to stream, and a 
single block that you could write yourself that inserts the cyclic 
prefix. Your task is surely to *understand* OFDM, so maybe plugging 
something together that gives you a valid CP-OFDM signal is what your 
advisor wants you to do?

Best regards,
Marcus
