Hi,
I am trying to build old version of gnuradio 3.4.0 on ubuntu 12.04 but i
keep getting these errors.
libtool: link: g++ -g -O2 -Wall -Woverloaded-virtual -pthread -o
.libs/usrp_rx_cfile usrp_rx_cfile.o
~/gnuradio-3.4.0/gnuradio-core/src/lib/.libs/libgnuradio-core.so
~/gnuradio-3.4.0/usrp/host/l
I want to use convolution code to transmit packet over USRP. So I ended up
modifying the generic_mod_demod in digital.
The original flow graph was
Tx
packed_to_unpacked(bits_per_symbol) ---> gray_encoder --->
differential_encoder ---> chunks_to_symbol(constellation)
---> rrc_filter ---> USRP

Hello,
In the current gr-digital/narrowband, I am using the benchmark_tx.py and
rx.py to test the bpsk communications.
It is found that the packet loss rate is very high (70% loss) in
discontinuous mode where every 5 packets are in a burst. But in continuous
mode, the paket loss rate is less than

Hi to all,
Do you have suggestions how to tame our ubuntu to perform better, untick
features?
We're using usrp1, even at 1 MHz bandwith the uhd_fft window goes gray
(in accessible) after a 1/2 minute, force quit and try again is the only
option.
The computer we use is smart enough to handle that d
It's cool! Thanks!

For me, I am very interested in that is there any open project to improve
the data rate and packet loss for the GNURadio based OFDM?
Some guys claimed that the LTE standards are implemented with USRP and PC
by SIMD programming. But their code are not open.
If GNURadio based OFDM can support high d
Hi,
I have two usrp conncted to host A abd B respectively. I want to send packets

OK, I see. The system is relatively unmodified
Is anyone out there using Nutaq's radios such as picoSDR? This company
took over Lyrtech who made the small form-factor SDR.
They have some interesting products.

The most exciting are the picoSDR and µSDR420 which support GnuRadio,
and have big Vi

Omer,
Can you run simple programs in GRC that don't use your square_ff? Just
create a signal source -> throttle -> wxgui sink program and verify that
works
