I am currently trying to transmit digital signals simultaneously from
the two independent sources using a socket connection to the digital
sources. Using the gnuradio-examples, I have been able to create a
script that does the transmitting of continuous signals. So, my next
step would be to send bursts of data asynchronously. I wanted to ask
if this is even possible due to the interleaving that must be done at
the USB. for example I have two sources, what will happen if one
source sends data and the other source sends NOTHING. from the
interleave.cc function,
for (int i = 0; i < noutput_items; i += nchan){
for (unsigned int n = 0; n < nchan; n++){
memcpy (out, in[n], itemsize);
out += itemsize;
in[n] += itemsize;
}
}
does the scheduler wait till there is data to send on both of the
transmit paths before it will do anything?
I made a script that sends data on SideA (RFX900), but not the other
(Side B - RFX400), and the data from Side A seems to be transmitting
(something) even though there is not any data going to the USRP from
SideB (which is what I want), but when I look at the data on a
spectrum analyzer the data is distorted (choppy in the time domain)
so in short...can I transmit asyncronous data using interleave?
thanks for any help,
David Scaperoth
