[Discuss-gnuradio] grc and wlan based ofdm

[maher manai]

i want to make a system bassd on ofdm modulation wich is wlan 802.11g or 802.11a so i want to ask if it's possible to do this in gnu radio companion (base band system, transmitter ,channel and receiver)  with all details such as scrambling encoding interleaving modulation ;  so i ask if any one can give me list of blocks that i need specially in creating ofdm symbols and inserting pilots subcarriers because i think that ofdm mod block wich exist dosn't support pilots subcarriers

thanks
