Re: [Discuss-gnuradio] IEEE 802.11 receiver not working for high sampling rates

Hi, well, the next step here would pretty clearly be going through the flow graph and finding out where things don't work – you'd typically start with something like a frequency or waterfall plot directly at the receiver, and then look for packet errors, and so on. Use a Qt time sink to look for c

Re: [Discuss-gnuradio] Python block help

Hi Zach, not sure the Python interface supports general blocks (ie. blocks where the number of output items is not a multiple of the input items), I hope someone else can comment; I'd recommend implementing this as a C++ block; the "Guided Tutorials" on http://tutorials.gnuradio.org should prepare

[Discuss-gnuradio] "LED" GUI widget?

I'd like to have an indicator in the GUI (just a small circle is fine) light up when a Power Squelch block opens -- basically, an "in use" signal. Is there a Qt widget that can do that, and is there a way to probe the Power Squelch for its state? (I'd like to do this within GRC if possible.)

Re: [Discuss-gnuradio] IEEE 802.11 receiver not working for high sampling rates

This might be a silly question, but are your gain settings correct? These two facts make me think you may be saturating the receiver and not experience sample flow issues: 1) You’re not seeing under/overflows on the output (I assume, or you probably would have mentioned it) 2) You *a

Re: [Discuss-gnuradio] IEEE 802.11 receiver not working for high sampling rates

Hi Victor, I am using GNU Radio flow graph and it's actually IEEE 802.11 modules wifi-tx for sending data. Also I am not using virtualized environment and my ethernet port is 1Gbps. On May 25, 2017 11:11 AM, "Diez Victor" wrote: > The problem could be the transmission of data via ethernet port.

Re: [Discuss-gnuradio] IEEE 802.11 receiver not working for high sampling rates

The problem could be the transmission of data via ethernet port. Are you working under virtualized OS conditions? These could be the origin of your problem, virtualized ethernet ports don’t reach enough high data rates. Another possibility could be that your ethernet adapter isn’t a gigabyte ethe

Re: [Discuss-gnuradio] Python block help

Hello Marcus, I realize this is a couple years later but I am attempting to do the same type of arbitrary ratio block, where samples above a threshold are passed and samples below that threshold are dropped. When I tried to subclass gr.block (as below, and in this tutorial from 2014

[Discuss-gnuradio] IEEE 802.11 receiver not working for high sampling rates

Hi, I am working with USRPs N210 and GNU Radio version 3.7. I wasn't able to work with higher sampling rate like 20 MHZ used in WiFi and that's why I bought a new workstation with better processor. However, the module still isn't working. The receiver isn't receiving anything at 20 MHZ if it's QAM

Hi Cinaed, Thanks a lot for the complete reply. I appreciate it. I will implement your suggestions and see what the output will be and let you know. Cheers. On 25 May 2017 at 09:56, Cinaed Simson wrote: > Suppose someone asked you to implement your flow graph on a transmitter > and receiver s

Re: [Discuss-gnuradio] Correlation Estimator Block

Suppose someone asked you to implement your flow graph on a transmitter and receiver separated by an air gap. Where would you tap into the signal with the Correlation Estimator? I would tap into the signal at the end of the receiver - at the virtual source with the decoded signal - or the very en
