cludes the propagation time and my
understanding so far is that the convolution tail of the FIR filter
was being "cut off" since there were no more incoming samples from the
message stream. Because of that, the last symbol was always
incomplete, so I figured this non-blocking adder would he

solve this in gnuradio?
There is also a git repository at
git://gitorious.org/~igoralmeida/gnuradio/igoralmeida-gnuradio.git
with the code applied directly to master, but I'm probably missing
some python dev files as gnuradio does not build.

/s), the
fft on matlab always shows a single impulse at aproximately -3kHz. In
the time domain, the signal is sinusoidal on both real and imaginary
parts, when I expect it to be only real since the carrier has (should
have) been removed.
I believe I am missing
fter the receiving USRP downconverts it from 2.5GHz.
The part of the signal which is supposed to contain the 2M wave shows
both real and imaginary sinusoidal signals, always close to DC by 3k
Hz or so. Am I missing anything?

Try running the program with -h so you can see the help message, e.g.:

I have recently had this kind of problem, so maybe I can help.
Did you make sure udev is working correctly and you have read/write
permissions to the block device?

Oops, sorry for this. I thought I sent the e-mail to the list but just
noticed only Johnathan got it.
I am posting it again hoping that someone can help.
