Hi,
a week a goo I asked if someone could please explain how the Rx MUX is
to be set, unfortunately I have not had any luck with an answer. I have
read the USRP FAQ but I find the answer unclear, e.g. because I do not
know the mapping of ADC number to side. In addition it is also unclear,
to me, i
Hello,
I am a newbie for the gnu radio. I am trying to transfer some
modulation/demodulation into Java, which can be used in my PhD
experiments.
My question is that I could not find gr_packed_to_unpacked_bb.cc file
in my downloaded truck of the gnuradio. But I do see the explanation
in the doxyge
hi all
i want to spread binary data read from a file using a PN sequence. The PN
sequence is generated by a LFSR. Is there any gnuradio block that can help me
do this. The gr.glfsr_source_b generates the sequence continously. If there
isn't any block that can help me do this, can you suggest a

I have some questions on tunnel.py.
1.) When this program is run from 2 different machines, which one is
considered as the access point? Or, rather, which instance actually sends
periodic beacon frames; is it the instance that was started first?
2.) Which Python/C++ program actually generates the
What does it mean that USRP2 can only do MIMO with eight receivers?
What are the options for doing MIMO with, say 16 receviers?
Why are there two A/D converters if you can only use one RX
daughtercard? Or can you actually use two RX channels with a USRP2?

You can connect the 1PPS to the digital io pins on the basic or lf
daughtercards. From there you can use the read_io() method in python
to read the value on the pins. Just make sure that your 1PPS is
between about 1.5 and 3.3V; under 1.5V it may not be detected, over
3.3V you could fry a pin.

Hi,
I want to give an external input to the old USRP board using a 1 PPS GPS
output. Is it possible to do so? if yes how?
Where can I access such external inputs in software ?
Thanx.

It could be anything. IIRC, I don't think the library code uses it by default.

We don't store one. The DC offset is automatically tracked and
subtracted out in the FPGA.

I apologize for the slightly off topic.
I had just received a donation from Intel of
8 quad-core XEON processors E5440 and I was thinking
of building a super fast gnuradio PC system.
Does anyone have an idea as to what is the best way to utilize these
processors to build a super fast PC system

use virtual functions instead of conditional functions in

Hi,
I thought I'd just drop some lines too (without actually being helpful :).
