Built and tested with Ubuntu 8.04 LTS Server version. All stock
packages with the exception of boost_1_37_0 that was built and installed
first. Built with all except 5 components as shown below. Tested with
USRP1 hardware.
Strong work!

Since you are going from B-PSK to Q-PSK modulation you may have a problem
with spectral inversion. With B-PSK it won't matter, however with Q-PSK a
+90 degree phase change will look like -90 degrees at the receiver.
You can invert the spectrum with the set_rx_freq command. Just set a
negative

That is a great reference book. The Matlab code actually works and
generates a fix. Here is a link to some Over The Air captures, including
GPS.

I'm attempting to run the fm_tx4.py sample. The code aborts with the
following error:
python: /usr/include/boost/shared_ptr.hpp:253:

The same error occurs when built with gnuradio-3.1.1.tar.gz or

For Ubuntu LTS 8.0.4 try
sudo apt-get install gsl-bin gsl-ref-psdoc gsl-doc-pdf gsl-ref-html
libgsl0ldbl
This will get you version 1.10-4

Another suggestion is to contact your local Xilinx FAE and ask them for
a copy of the tool set for the larger FPGA. Also ask them why they
don't include the larger device in the no cost Web Pack. I never
