Hi All,
I am going to TX/RX using OFDM. However, I am using Ubuntu 8.04 and
Gnuradio3.1.1, there is no OFDM package included. How should I include the
OFDM package?
Thanks,
Brook

Hello Fernando Perez-5,
I am trying to install OFDM too. Do you have any clue on how to include
those OFDM files to your system?

Are there any examples of how to use this?
Since the current C++ (until C++0x is out) doesn't support vector
initialization, how does one format the inheritance constructor?
for example:
myblock::myblock(...) : gr_block("myblock", gr_make_io_signaturev(4,4,
std::vector somevec)) { ...}

set_freq would not be a good measure, since it takes a while to
configure the daughterboard. find() isn't great either, since it
waits 10ms to ensure that it's gathered all responses to it's
broadcast.
set_rx_decim should give a reasonable measurement, as long as you're
not streaming data.

Hi everybody!
I have modified usrp_spectrum_sense.py to plot the results with gnuplot.
There are two files: widespectrum.py and plot.p
I would like everybody to test it and report me the errors and how can I
improve it.
I've used USRPv1 + Flex2400.
Thanks in advance!

Hi,
If USRP2 can respond to PING and reply back, then one should be able to measure

Hi,
If you installed boost at (for example):
/opt/boost_1_36_0/lib
then :
1) sudo edit :
/etc/ld.so.conf
2) add the line:
/opt/boost_1_36_0/lib to it
3) exit and do:
sudo ldconfig
