Hello every friend,
Could I spare you a few minutes? :) My Teammates and I have learned to develop
an application using B200mini on Android. We followed Mr. Tom Trondeau
instructions on http://gnuradio.org/redmine/projects/gnuradio/wiki/Android that
very helpful for our work.
Here are some ques

Okay. If I understand you correctly, then if I have a GRC flow-graph which
consists of both uhd usrp source an

Hi Josh and others,
I have some more questions related to DUC/DDC cordic, USRP tuning process:
1) When an eob tag is issued, the DUC phase accumulator on transmit DSP chain
is reset. What about the DDC phase accumulator on receive DSP chain? Does it
reset at well? I am asking because I have see
Hi all,
We are currently trying to send time-synchronized packets from several
transmitters, and we are having some difficulties with the transmit
time-tags. Especially, we have trouble understanding what happens with the
flow of samples when transmit time-tags are added to certain symbols:
Hi Bomi!
Don't know if you still need this but there is a block in GRC called
Rational Resampler, try using that combined with the USRP2's decimation (for
example Decimation 4 and Rational Resample rate of 8/25 for a 8M band) for
trimming your baseband!
HTH.

Did you see the warning it prints? It contains the instructions.
Instructions to resize the kernel socket buffers are also here:

Hello :)
I am trying to implement the relay system with USRP2 & RFX 2400.
I am using GRC+UHD.
(GNUradio 3.3.0 , UHD_003.20110310224233.4c7cc6b)
When UHD is used in some cases, the comments come up as below.
(1) Target recv sock buff size: 5000 bytes

Hello, Bomi. Welcome to the new world!
1. USRP2 uses GbE(gigabit ethernet) interface to transmit and receive
data(raw samples and control messages). It has a UART available, but you
cannot see it unless you open the case.
2. The term 'reliably' largely depends on the circumstances. Especially on
Hello. J
I am a novice usrp2 user.
So my questions might do not make sense.
I hope you understand me.
1)
I wonder how USRP2 transmit and receive the data with host(com).
Which UART model does the USRP2 contain?
2)
How many samples does USRP2 transmit to the host reliably?
Is the sa

Hi,
I have the following questions,
1. I found the usrp2 box, not responding on certain Ethernet cards?
Means, will it only work when connected to some Gig-bit Etherent cards,
found when connecting on the certain 10/100M ethernet cards, not
responding when tried the find_usrps.
2. Am compile
Yes, that's what I meant about sdcc-nf:
Jaunty had sdcc 2.8.0 which was divided into sdcc and sdcc-nf (non-free)
Karmic has the new sdcc 2.9.0, which is re-licensed under GPL3, so
there's no -nf part
Updated the automake and sdcc issues on the wiki, left the subversion
and guile as is...

Hi,
I've got my custom block producing mono audio at 8KS/s which I am sending to
an audio_sink(8000, "plughw:0,0") and have some questions.
First question: what is the range of values that each output sample can
assume before clipping? Since they're floats I am assuming its -1.0 .. +1.0.

Hi all,
I am a newbie at GNU Radio, and I am in the beginning of my bachelor's

try to use this code to do some implementation.
Currently i use XCVR

Thank you for the clarifications.

Hello,
I am new to GNU radio. So far I have been playing with benchmark_rx
and benchmark_tx. Now, I am trying to estimate the distance between the
transmitter and the receiver. For this I need a very accurate timestamp on
my packets. So my questions are-

hey everyone
I just bought 2 USRPS and 2 daughter boards ( RFX 2400)
and Im intending to implement the IF and RF stages of wimax, the usrp will
get its
data from a previous stage which is on a TI DSP . Can someone answer me some
questions,
how can i test my USRPs ? i already
