I’m co-writing a paper on the use of GNU Radio. Because I’m inclined to
use ‘Open Source’ solutions,
GNU Radio and the attendant DSP library, was for me about the only
choice I would have made…
However, in the paper I’d like to at least make some attempt at
indicating any ‘alternatives’, if there
are any in the Open Source arena, or parish the thought, cost-money type
High Performance Software Defined Radio (opensource)
An Open Source Design
The HPSDR is an open source (GNU type) hardware and software project
intended as a “next generation” Software Defined Radio (SDR) for use by
Radio Amateurs (“hams”) and Short Wave Listeners (SWLs).
There are GnuRadio developers which are in contact with or collaborate
with people of HPSDR.
They use some of the verilog sourcecode of the USRP for their FPGA in
Gstreamer Quadrature library (opensource):
libgstiq is a library with Gstreamer plugins for use in software
libDSP is a C/C++ library of digital signal processing routines,
including standard vector operations, digital filtering, and transforms.
Company building software defined radio frontends (SDR-1000) for use
through the soundcard of a PC for the IF.
Aimed at Radio-amateurs
Hardware oriented commercial company delivering blocks to build SDR
ComBlock modules are small commercial off-the-shelf modules which are
pre-programmed with essential communication processing functions,
including modulation, demodulation, error correction encoding and
decoding, digital to analog/RF, RF/analog to digital, formatting, data
and baseband interfaces.

who has something that works, I’d also
like to know about that.
Thu GnuRadio GUI you are referring to is called GRC, written by Josh
For those who have information, and send me a release, credit will be
made in the paper for their contribution.
If you need any other kind of info, please let me know.
I have done some presentations on GnuRadio and Software Defined Radio
and I am preparing for some GnuRadio courses that I will be giving.
It would be appreciated if you made the paper public and available
somewhere on the web.
