Re: [Discuss-gnuradio] build error: test_gruel.o: undefined reference to symbol 'boost::system::get_system_category()'

I have been able to work on this tonight, and I think the solution is that we just needed to be more specific in our LDADDs in a few places. Mostly, it's where we are building programs (noinst_PROGRAMS = ), but we were only passing an LDADD of a few libraries and not everything. I was wondering

Re: [Discuss-gnuradio] laser and infrared

We're using the USRP+GNURadio to do passband modulation of a LED and/or laser. We run the signal from the Basic-TX daughterboard into an amp and a bias-t and then into the laser. At the receiver we take the output directly into the Basic-RX board. Works pretty well. On Thu, Mar 31, 2011 at 10:02

[Discuss-gnuradio] why changing decimation in benchmark_rx.py affects SNR so much?

I'm running a link via benchmark_tx and benchmark_rx files. They are both running at 1e6 symbols/sec and a 5 Mhz carrier. The settings are default otherwise. I've noticed that when I change the decimation rate at the receiver, the SNR changes quite a bit while keeping BER the same. I would think wi

I'm currently using GNU Radio for an application in Visible Light Communication, which has similarities to IR. Since both are IM/DD, I use the LFTX and LFRX daughter cards with USRP2's and I've been working on implementing some baseband modulation techniques. I was also able to test with so
