Hello
We are at Aalborg University currently working on building a USRP1
based testbed for OFDMA requiring FDD/full duplex as well as TDMA
(using timestamp functionality).
In an earlier post, dated 02 Mar 2009, it was mentioned that for USRP2
some modifications had to be made for the firmwa

aha, you have fedora...
1) build guide: http://gnuradio.org/redmine/wiki/gnuradio/BuildGuide
2) fedora specific: http://gnuradio.org/redmine/wiki/gnuradio/FedoraInstall
3) yum install:

I tried installing from the tarball that i downloaded from the link given below
by you but when run ./configure , it says
Checking for ...
... ... ...
Checking for Cppunit - version >= 1.9.14... configure: error: GNU Radio
requires cppunit. Stop
and when i run 'yum install cppunit', it says,
I made the following simple example using the fir interpolation filter:
input sequence x=[1,2,3,4,5]
interpolation = 1
channel h=[1]
output sequence y=[1,2,3,4,5]
channel h=[1,0]
output sequence y=[1,2,3,4,5]
so far so good.
Now I changed to
interpolation = 2
channel h=[1]
output sequence y=[
Hi,
I made a lower level c++ implementation using the code from
rx_streaming_samples.cc in /usrp2/host/apps and manually put in a tx
before the receive portion and it works fine. It seems the issue is
related to noutput_items in my gr- module. As I stated above it uses
8162 for noutput_items for wh

Hi, everyone
I want use the hydra architecture for our MAC protocol design.
When I browse hydra code, I see some code like:
inline gr_msg_queue_sptr inputQ() const { return d_tx.inputQ(); }
inline gr_msg_queue_sptr ctrlQ() const { return d_rx.ctrlQ(); }
inline gr_msg_queue_sptr outputQ() const {
11 matches
