Hi,
I have noticed that all the file sources in the latest stable and unstable
Win32 builds are broken.
It appears that the file path is not escaped properly. Is there any news on a
fix for this?
Regards,
Mark McCarron
Unfortunately I wasn't able to determine the problem after a quick glance. I
recommend that you use gr_modtool to create an out-of-tree module and then add
a block to it. This will set up most of what you need. Then you can splice in
your code/algorithms and not have to worry as much about the b
Hi
I have been trying to demodulate a vector of data sent using a file source
using qam demodulation on the grc. I am stuck as i don't recieve anything
on my output file source. The output file is blank.when I change modulation
schemes like gmsk,qam or bpsk or dqpsk, there is a very small change i

i use the following command to capture some samples of noise
uhd_rx_cfile -a serial=4759a751 -N 10 -f 2.48G --samp-rate=2M noise.dat
then using matlab i read the samples
y=read_complex_binary ('noise.dat');
and i do plotfft
plotfft(y,200)
the plot shows a peak near the center. I don't

if i have understand i need to use the --lo-offset of uhd_rx_cfile
i have gave various values to --lo-offset and only one value has moved the
DC offset (--lo-offset=1G) and the plotfft gives many small spikes (maybe
this is caused to aliasing, but i am not sure)

Hi list
Does there exist a way to gate integer variable update events in GRC
if their values aren't changing? Example:
Function Probe 10hz -> my_var -> 1, 1, 1, 1, 1, 1, 1, ... etc
Probe is sending update events even if value passed to myVar doesn't
end up changing, as a result the desti

Hi All,
I'm playing around with digital modulation techniques in GnuRadio and
would like to get a sense of how successful my efforts are in terms of
BER vs. S/N ratio.
Can someone suggest a reference that provides BER vs S/N ratio curves
for some of the common encoding approaches?
Thanks,
-Greg
