Hi I was also looking around the OFDM Modulation recently. Found this nice project here: http://people.csail.mit.edu/szym/rawofdm/README.html where ofdm mod and channel est are done separately. I didn't had the time to follow ths more...perhaps it helps. best, friederike On 01/20/2012 02:38 PM,

Did you solve it? I am trying to add FEC in the OFDM chain but I didn't figure out how to do this, yet. Any advice or do you know if someone did it and the code is public? Thanks Veljko Pejovic wrote: > > Hi, > > I tried to use trellis_encoder from trellis package to perform > convolution co

Hi, I tried to use trellis_encoder from trellis package to perform convolution coding before sending the message to the OFDM modulator. However, ofdm_mod has zero input signature, and relies on send_pkt() which calls ofdm_packet_utils.make_packet() and then puts the message in the queue at gr.ofdm
