Regarding ofdm modulator and demodulator block

[Rozana Alam]

Dear community,
Is the ofdm modulator and demodulator block removed from the gnu radio
3.7.0 version? I want to analyse simple ofdm modulated signal in different
frequency and bandwidth using spectrum analyser and usrp. Please help me
with your guidance on this, as a beginner with gnu radio and SDR I really
need your suggestion.
Thank you.
Sincerely,
Rozana
