Hello sumit,
Thanks for your help i went through that document that you refered to, and i
tried to implement that OFDM transmitter part. This document only explain
about OFDM flow graph or transmitter. Is there any other document or
information related to OFDM modulator and demodulator (Transceiv
Short answer: You cannot open a new USRP instance to reconfigure an
already-running USRP instance. You must reconfigure the existing instance.
The best advice I can give is that only one flowgraph can be operational per
USRP device. In your setup, USRP#1 will run a single flowgraph with a source

Hi,
I found a bug in the 'gr_tagged_file_sink.cc' file during my work on a burst
detection.
Line 203 should be changed to:
203 int count = fwrite (&inbuf[d_itemsize*idx], d_itemsize, noutput_items-idx,
d_handle);
The original code was:
202 if(d_state == IN_BURST) { 203 int count = fwrite
Hi, Nick, Vadim, Josh,
I got the same problem with two N210 in my institute, that only LED B & F is
on.
I tried to reprogram the FPGA following the thread "Bricking and recovery of
N210" but it remains the same?
Have you found how to work it out?
Cheers,
Hanwen
