Hi
What kind of sink can be used to analyse the outpt of a PSK modulator. I am
transmitting a text file and is trying to retrieve and analyse using file sink.___

Hey everyone,
right in time for Midtermevalutaions I have a bigger update for you.
Viterbi Decoder is now fully Volkified, but results are a bit meh :/

Deal all,
Does anyone update the Channel Coding (https://www.cgran.org/wiki/chancoding)
toolbox so that it can work in Gnuradio 3.7.0?
I did try to install this toolbox. The installation was done but it do not
appear in Gnuradio Companion interface.
Thanks,
Hoang

For initial experiments, the waterfall source would be a nice choice, as
it displays energy over frequency and time.

I am facing a funny issue: I want to use the sound card for analyzing the

Hi JM,
guessing in the dark: You are likely running a modern linux
distribution. Many of these tend to emulate an Alsa device, which in
fact is but an Pulseaudio server, which in turn speaks to the real
device. They set that as the default audio device in the system.
Have you tried using the
Hello,
I'm doing a block with two inputs (signal and noise) and one output.
Signal input block generates samples sometimes. For example:
2,3,-,-,4,-,-,-,5,1,1,-,4,55...
Noise block generates samples always. For example:
1,1,0,2,2,1,2,3,4,2...
I want to create a block that adds noise to the
Thank you Marcus.
I've checked out gr-fec. The problem is that Decode CCSDS 27 block takes
float input while my data to feed it is in byte.

Hi Caruiz,
you don't even tell us what goes wrong, so it might be hard to answer
your question ;)
Anyway, that's not how GNU Radio really works. For the sample streams,
real time just happens to pass by and has no meaning. So the concept
generates samples sometimes doesn't exist in GNU Radio --

I believe your problem could be easily solved.

Really clear your explanation Marcus :)
Activecat, my input block
is a variable delay.
- I have a signal recorded in a file.
- Signal
enters in a variable delay (delay is controlled by another block).

Signal enters in Add noise block.

The radar toolbox has new features! GUIs for scatter plots of two target
attributes and time plots of a single target attribute are implemented.
All GUIs are real time and multi target capable.

How did you install GNURadio? The error suggests to me that performance
counters were not enabled at compile time. There is some information about
enabling performance counters on the wiki page:

Good luck,
