I have made good use of GRC under Ubuntu (it suddenly quit working under
FreeBSD) for some projects. Currently, I'm trying to get a QPSK receiver
running at 1.92 ksps or slower. Send me .grc file for the demodulator
part and tell me how to tweak the variables.
I'm pretty sure *someone* can help you with the QPSK demodulator on this
list. I'm not the guy.
My DSP expertise is limited (mostly) to that which is required for
applications in scientific radio,
including radio astronomy, ionospheric monitoring, etc. Hardly any
cosmic objects modulate
themselves in QPSK, vanishingly few, in fact :-)
But the people who developed most of the DSP blocks in Gnu Radio are on
this list, and are happy
to help people use their work. It's true that better per-block
documentation is still required, but
again, people in a community-oriented project like this work on what
they want to work on. That
may not include really-good documentation. Not all programmers are
also good documenters.
