Re: [Discuss-gnuradio] gr-cdma doxygen build

Thanks for your reply Achilleas. Do you have a compiled version of the documentation you could share? A pdf or html format would be very handy if I can't solve the problem. Regards, Murray On 29 March 2017 at 18:21, Achilleas Anastasopoulos wrote: > Hi Murray, > > although I

Re: [Discuss-gnuradio] gr-ieee 802.11 and commercial AP (late ACK packets)

An interesting question is whether more powerful SDR (e.g. E310) should manage to do that (DATA+SIFS+ACK). RFNoC may facilitate the FPGA design... 2017-03-29 17:19 GMT-03:00 Bastian Bloessl : > Hi, > > On 03/29/2017 01:11 PM, sumitstop wrote: > > Hi, > > > > With gr-ieee

Re: [Discuss-gnuradio] [GSoC] GNU Radio Companion Extensions: Output C++ Code

There's another thing: On 3.8, we'll be going to a different model of writing GRC bindings (YAML-based). It's difficult to summarize the changes, but basically, don't assume that we'll be using XML files forever. -- M On 03/29/2017 08:52 AM, Ben Hilburn wrote: > Hi Håkon - > > Welcome! I'm

As said, Hannu just as the gr-osmosdr project, which already has an SDRPlay interface, have the same legal trouble: since the SDRplay library is not GPL-compatible, neither can ship binaries, just well-portable code :( On 03/29/2017 07:39 PM, Arie Kleingeld PA3A wrote: > > Yes Hannu, > > I have

Re: [Discuss-gnuradio] Perfect Reconstruction Filter and GNURadio

Hi Bruno, welcome to the mailing list! Interpolation and Decimation filters are fundamental components of GNU Radio. Just use a "low pass filter" with a "decimation" or "interpolation" that is not 1. How to do that is covered by reading the guided tutorials: http://tutorials.gnuradio.org I

Hi Murray, although I am the author of gr-cdma I do not know how to help you with this. I am using doxygen etc as a user, not a developer, so I wouldn't even know where to start. For what it's worth, I have developed and tested this module on Fedora 21. Hope someone else in the list can help on

Hi! My name is Bruno, i'm from Rio, Brazil. I'm a master's student in electrical engineering, applied electromagnetism. I need to do a home work about perfect reconstruction filter, interpolation and decimation, using GNU Radio. Could you direct me to some GNU Radio articles on the subject?

Hi, With gr-ieee 802.11, I know that SIFS cannot be respected becz of USB delays (B210), but what we can also try is that : sending ACK packet before all the layer-2 retries are exhausted ! Instead of sending ACK withing 10 microsecs. In this way, the throughput will be down for sure but the
