Hi, I'm currently completing my thesis year at uni, and am running out of time
to complete.
My question is, how easy/hard is it to create a digital 2Tx to 1Rx antenna
configuration using two USRP boards and the BASICTX and BASICRX daughterboards?
I am hoping to have a MIMO SDR system implementin
Thanks, that helps some.
I figured that I could put in the literal size of the data, in bytes, but that
only helps if it actually matches how the GR blocks are going to process those
bytes.
When possible, I would prefer to use the constants that have been set up so
that the code is (1) more re
Hi!
First of all, excuse me for this beginner's question. Furthermore this is a
little bit offtopic.
I have copied gr-howto-write-a-block and adapted everything to my needs.
Now, in the Makefiles, it says "This file is part of GNU Radio". But my
project is not part of the GNU Radio framework, and

Is it possible (in a relatively easy manner) to make the data from the ADC (or,
probably better and more doable, from the DDC) available at the external pins
of the USRP and to get external data from the USRP pins and feed that to the
PC? Essentially we want to use the FPGA board as a front-end
I have a few questions, but they mostly come down to: What is the data file

Thanks for all the responses from everyone.
Right, it has a BNC, that was my mistake.
I pretty much have no supplies other than a ton of SMA cables that were
purchased for the USRPs. So I'm building up my stash :)

Does your scope really have and N connector on it? Most use BNC.
Adapters are nice to have but you can have a custom cable made up

Hi George
I usually get my electronic stuff from digikey.com, in one of my last
orders I go this adapter for about $11.50:

I think Universal Radio has some decent stuff, but they may not have
EVERYTHING you're looking for.

Thanks, but I'm looking for a c++ app.

Thanks for the information David. I will look up ITU-J.83B ...
Do you happen to have any captured QAM cable data (or any website that
lists the data) ? I wanted to see if I can put together a software
demod for digital cable ...
