[Discuss-gnuradio] aligning received ofdm frames

[Shane Petcavich]

Hello,

I'm using the attached two grc files for OFDM transmit and receive. I need to align a received symbol with the corresponding transmitted symbol to perform some math. From this link at the bottom it looks like the header meta deta that is passed back to the header demux block contains information such as the packet number, which may be useful. Is there a simple way to sink all received symbols / packets to a file and extract the meta data out to align each transmitted symbol with its corresponding received symbol?

Thanks
