You'd need to write your own block that can handle these formats.
A word of warning: When doing SDR, you deal with MEGASAMPLES per
second.
A 32 bit floating point number has circa 9 significant digits.
That makes 10 characters when you include the decimal dot.
Then you also need to write down the

Dear all
I am working on B200 USRP for sensing the ISM band spectrum.
My parameters is 2.4 G - 2.5G, FFT size 1024 (6.4MHz), sampling rate 40e6,
taking 832 bins of 1024 from 96th bin to 928th bin, totally 19 subbands, each
of 5.2 of 6.4 MHz, and frequency between two bin values is 6250Hz.

Hello Everyone
I am a new to gnuradio. I would like to do simulation of spectrum sensing
(Simple energy detector with single band only).
Normally I have seen "usrp_spectrum_sense.py". However, that is written for
USRP (and not easy to understand and modify it). Actually I have a difficulty

Hi Przemek,
well, since this is the open source world, you shouldn't need to write
everything from scratch.
You can of course start off with Martin Marinov's source code,

which will give you an tcp server

I would like to do spectrum sensing with GNU radio. Is there a good way to
get the raw output from uhd_fft.py (the value for each frequency)? I would
like to do this programatically (with code), rather than through a GUI.
I have tried doing spectrum sensing with usrp_spectrum_sense.py, and this

I am actually doing something similar for cognitive radio, the best way to
go about it is to follow the tutorial online for how to write a signal
processing block

find a little vague on some parts); you can browse google for a

Hi all!
I'm starting to work on a project and first of all would like to know if
it'd be possible or what recommendations anyone has on it.
Basically what I want to accomplish is the following:
Host A: USRPv1 + RFX2400
Host B: USRPV1 + RFX2400
Both hosts would:
1) Always scan for the wireles

Does that mean 8Mhz is the max. width of spectrum I can sense? But I
remember reading on some post that we can sense spectrum upto +/-15MHz
from the carrier frequency. (i.e. a chunk of 30 Mhz). Which one of the
above is correct? What puts a limit on the maximum amount of spectrum
we can sense?

Hello everyone,
I was going through some gnuradio documentation (on comsec.org wiki)
which says "...16-bit I and 16-bit Q data (complex), resulting in 8M
complex samples/sec across the USB (32 Mbps max. data rate). This
provides a maximum effective total spectral bandwidth of about
6MHz...".
