Re: [Discuss-gnuradio] HELP!!! USRPN210+GNURADIO

2015-12-01 Thread Harold Daniel Moreno Urbina
Like one year ago I was testing with USRP N210 with the blocks attached to this message. Note that one is for transmission and the other one for reception. I am lucky and I got 2 USRP N210, so I was able to send a tone (one sin function or the add of two sin functions) and receive it correctly. If

Hello, Have you tried with just raw data?. I mean, use a file with data you already know, for example in a file, make the proper modulation, send it over the air, receive the data, put it into a file, compare both files. I can guess that the problem is in the decoder in the receiver part. Study a

2014-08-31 Thread Harold Daniel Moreno Urbina
As stated on http://code.ettus.com/redmine/ettus/projects/uhd/wiki/GNURadio_Linux the installation of gnuradio will not necessarily install all dependencies. They recommend to run sudo apt-get install python python-wxgtk2.8 pyqt4-dev-tools python-qwt5-qt4 python-numpy libboost-all-dev libusb-1.0.0
