[Discuss-gnuradio] Changing the installation directory for GR

Hi all, I have been using gnuradio on Ubuntu 12.04.1 LTS that I installed via the 'build gnuradio' script and it has been going well. I use it for a number of projects and wanted to have a separate copy to change some of the code so I downloaded the latest tarball, extracted it to a directory

2012-11-06 Thread Ben Gear
All, Can anyone tell me if there is a way I can measure the rate at which a flow graph is executing when it contains no rate limited blocks? My motivation for doing this is that I wish to benchmark a signal processing chain so that I can estimate the maximum bandwidth I can expect to process

I've been working with the OFDM examples that come with GNURADIO (benchmark_tx.py and benchmark_rx.py). I've noticed that my bit error rate (BER) increases as the length of my cyclic prefix (CP) increases. This is opposite of what theory predicts, since larger CP decreases inter-symbol
