Thanks!

I wasn't getting anything through.
My USRP Sink block had an empty TSB tag name property. I didn't have a TSB
tag name = packet_len property. I started getting data across after adding
that.

Hi All,
I am doing an OFDM transmission with tx_ofdm.grc and receiving it with
rx_ofdm.grc. I am using two USRP N210s for this.
I edited the tx_ofdm to set the transmission rate to generate 96-byted
packets every 10ms via : message strobe-> random pdu generator->pdu to
tagged stream.
However, n

Hi All,
I am doing an OFDM transmission with tx_ofdm.grc and receiving it with
rx_ofdm.grc. I am using the Random Source of the tx_ofdm unmodified. I want
to be able to control the packet transmission rate - for e.g. 10 packets
every 100ms. How can I modify the grc to be able to do this ?
Thanks!
Thanks Marcus - that helps.
Could you please let me know what's the bandwidth of each sub-carrier? How
can I calculate that and reconfigure the same?

Hi Marcus,
Thanks for the email. I connected the debug tag to OFDM Channel Estimation
and noted that the ofdm_sync_chan_taps key has 64 complex values.
Could you please confirm the following two things ?
i) These 64 complex values (a + ib) represent the 64 sub-carriers and I can
get the amplitude
Hello all,
Could you please let me know how I can get channel-frequency response (like
channel state information (CSI) ) for an OFDM transmission? I am looking at
rx_ofdm.grc to capture the phase and amplitude at each of the 64
sub-carriers.
Would connecting the OFDM Channel Estimation Block of t
