Hi all,
I am using two RFX2400 daughterboards on USRP1 to implement TX/RX on each
daughterboard.
When I do ZigBee packet transmission, I found that there are always some
trailing garbage signals after each packet. The trailing garbage has strong
fixed I and Q values (slightly changing) which la

Hi all,
I have been building a simple block that can detect energy at a
particular frequency, i.e. a tone detection block. The signal
processing seemed simple enough for me, so I directly coded it.
Essentially my tone_sink takes in float point samples of the input
signal (passed through a
Here is a typical work function:
int work(int noutput_items,
gr_vector_const_void_star &input_items,
gr_vector_void_star &output_items)
output_items seems to be a pointer to a pointer into some pre-allocated
memory. What is stopping me from managing
My boost version is 1.42,still it gives the same error. I am still at the
./configure stage.I think I should use sudo command after ./configure is
successful,am I right?Thank you for all your help.Regards,Reena

it works fine now( thank you zerocool :)),but now I get some : "conftest.err :

Great! If you can survive without the filtering, you're actually better

Hi,

So, a couple of questions please,

I read all the documentation concerning the trellis, and the final idea that
comes to me is to write a code like the following (to implement the
convolutional decoding 1/2, poly 91,121, constraint len 7):
input_length = 48
output_length = 24
src_data = [1.0 for index in range (i

Hi Eric
Here some information for you:
C++ Code:
#include
int main ()
{
usrp2::usrp2::sptr u2;
int count = 0;
while (count++< 3)
{
sleep(3);
u2.reset();
u2 = usrp2::usrp2::make("eth0","");
}
return 0;
Dear List,
We are heading to the end of February, what is the status of the message
passing functionality between blocks? I've been looking around in the
developers branches but haven't found anything yet...
Can someone update me, please?
Best regards,
