The throttle block has some peculiar limitations. For example, if you try to set the throttle very low (like < 1k) you'll find that there is minimum threshold and what will happen is it will still give you way more samples than you expect. Before I found the head block, which allows you to

Hi Vicfield, I actually work on the ground system that receives these signals. They are distress signals from different beacons: EPIRBs (boats), ELTs (planes), PLBs (hikers or anyone who wants a handheld device) that are captured or relayed through satellites to the ground. This allows rescue

[Discuss-gnuradio] OpenCL FPGA Recommendation?

Hi everyone! I'm working on expanding the OpenCL modules for GNURadio and I want to test them with some FPGA's that support OpenCL. There's a few from Xilinx and Altera it looks like, but the ones I've seen are a bit pricey. Does anyone know of an OpenCL-capable FPGA card for under $1,000 for

Hi Fernando, You are assuming that the signal you are getting at the receiver is not delayed with respect to the one being sent. You are thus using a cosine signal source with no phase correction. This is not true, since you are using filters, which always delay samples (moreover, you should make

I am trying to do an install of gnuradio into a directory on my company's share that I don't have the ability to change. I thought it was working until it hung for a while. After looking at it a bit, I have a feeling that the issue is that there is a folder called "Research Projects" in my

Hello, Victor: Thanks for your information, I exactly tried to decode the file with the real EPIRB signal from a PLB, although I’m pretty suspicious about that is beyond me too much… But it is really surprised me that what you said: The signal "trigs" detecting is too complicated to implement

I'm not familiar with that exact flowgraph, but nothing will "break down" in a CPU only flowgraph. Drag the ctrl port perf monitor block on to the flowgraph and look for the avg throughput counter for a block you care about. It'll give you items/sec. PS - the throttle block only gives you an

Hi Fred, this is a warning that you want to execute a 'No GUI' flowgraph without a terminal. GRC tries to run your flowgraph by opening a new terminal. All prints etc. will go into this terminal. But GRC is missing the path to your terminal application. How to fix this: Go to ~/.gnuradio

Dear all, I wondered what would be the maximum sample rate that my PC can handle for a basic psk mod-demod. I have used the “prbs_test.grc” from gr-mapper as it contains all the necessary blocks. I changed the sample rate for the throttle to 32k, 320k,10M, 100M even 10G but the system did not
