Frank,
I just commited an update on fsm_utils.py where I added two
helper functions:
fsm_concatenate(f1,f2)
that concatenates two FSMs into one (this is what you need in your project)
and
fsm_radix(f,n) which generates the equivalent FSM resulting from
operating the original FSM for n steps.
Ach
Hey all,
I'm looking for some help building features/inband-usb
Eric and I couldn't exactly figure out what causes this at the hackfest, and
I've spent
some more time with it and still can't figure it out.
the root of the cause is in usrp/host/lib/inband and usrp_rx.cc
it builds, but does not
Frank,
this is a nice example of combining 2 FSMs to create a
bigger one that describes the overall system:
The DQPSK can be described as an FSM with inputs x and outputs y.
Both x,y are integers (not complex numbers).
Then the ISI channel can be thought of as another FSM with input
y and output

I've just installed gnuradio from subversion on Ubuntu Feisty, per the
instructions at http://gnuradio.org/trac/wiki/UbuntuInstall. Everything
seems to have gone ok, but when I try to run the benchmark in pthon, I
get:
undefined symbol: _Z20gr_make_io_signatureiii
Any idea on where I might have

here is an application that requires significant FPGA

Hello,
I am new at dsp and I hope that I do not bother you which a
stupid question:
I want to use the gr_trellis block as an ISI equalizier for a
burst type (pi/4)-DQPSK system. Therefore I have two questions:
1) I think that I know how I have to expand the fsm_utils.
make_isi_lookup() function
thanks, that really clarifies a lot of things for me. I'm slowly beginning
to understand the inner workings of the FPGA. Thanks again.
