Re: [Discuss-gnuradio] QPSK Receiver and Processing Power

Hello Rich, although Ed commented on the latency issue, regarding your performance issue my 2 pence: From my experience, using a time domain equalizer with 100 taps is a huge computational burden. Imagine: You are expecting significant echos (to be equalized) of 100*4/250kHz=1,6 ms. I do not

Re: [Discuss-gnuradio] eye diagram error

I'll add one thing to Marcus' recommendation: turn on persistence in the scope widget. Then you've got a great eye-diagram! Very Respectfully, Dan CaJacob On Thu, Feb 19, 2015 at 4:33 AM, Marcus Müller marcus.muel...@ettus.com wrote: Hi Mostafa, yep, these are not GNU Radio core

Dan, You can turn persistence on!? I use qt widgets, I don't see that option in the Time Sink. Is this a WX only option? v/r, Rich On Thu, Feb 19, 2015 at 12:36 PM, Dan CaJacob dan.caja...@gmail.com wrote: I'll add one thing to Marcus' recommendation: turn on persistence in the scope widget.

Re: [Discuss-gnuradio] eye diagram error

Hi Mostafa, yep, these are not GNU Radio core visualizations, but come with gr-baz. You might be using a GNU Radio 3.6-compatible version of gr-baz instead of one that works with GR 3.7. Make sure to install the master branch of github.com/balint256/gr-baz , after removing all remnants of the

[Discuss-gnuradio] Code of USRP experimental setup of full-duplex radio

Hi everyone, I should create a testbed with USRP2 devices or stimulate a full-duplex environment with ns-2. So, I need the code of experimental setup to implement a practical 802.15.4 full-duplex radio or any full-duplex environment. If possible, can you provide me with the code of USRP

Murray, thanks for your idea which I'll use if I need to avoid the gentoo emerge utility. Rick, thanks, Bug 540658 was just posted. I hope the problem is simple to solve - and also not a blunder on my end. :-) Thanks, guys! Mike On 02/18/2015 10:47 PM, Rick Farina wrote: Mike, I am the

[Discuss-gnuradio] GPSDO and B2100

Hello, I recently installed a board mounted GPSDO (TCXO) on my B2100. Specifically I am using this in a USB powered mode and the web-site did say that the TCXO works off the USB power. I am using a passive antenna at the moment. Now most of the time I get warning display No GPRMC message found.

Re: [Discuss-gnuradio] QPSK Receiver and Processing Power

Thanks Stephan, that was a very good point to make. I have reduce the number of taps in my equalizer. Unfortunately, this hasn't fixed the issue I spoke of (surprisingly). I am seeing dropped packets at sample rates of 200k, on and off, and HUGE latency between making a change at the transmitter

Re: [Discuss-gnuradio] how to schedule iq recordings?

I just use the at linux command to schedule my recordings. Your script can handle the timestamps, gain, antenna settings, etc. For example, to run bash_script.sh at 04:00 # at 04:00 -f bash_script.sh To see queued executions, # atq This works really well for me. PWG On 02/08/2015 02:42
