CGRAN: new projects added & updates

Hi all,

For those of you unfamiliar with CGRAN, it is a host for 3rd party GNU
Radio
applications: https://www.cgran.org

Just to settle some quick confusion, you do NOT need an account on CGRAN
to
checkout a project. You only need an account if you wish to make wiki
or
code changes. So, you are free to checkout any project anonymously :slight_smile:
Though, I appreciate if you register anyways, it gives me an idea of who
uses CGRAN!

We are ALMOST to 100 registered users, currently at 94! Its success is
great, I’ve read a few published wireless papers this year that used
code
from CGRAN for their project, and in some cases even cited CGRAN :wink:

Thanks to all who have contributed to and used CGRAN!


New Projects

Smartnet Trunking Receiver (Nick F.) - This module implements a
receiver
for Motorola Smartnet trunked radio systems. It replicates most of the
functionality of a simple trunked scanner, and you can also use this
module
to receive the entire trunked network in real time and log it to disk.
Typical scanners are limited to receiving one channel at a time.

IT++ Wrappers (Martin B.) - This module attempts to wrap IT++
function
into GNU Radio blocks. IT++ is a C+±based library for running
communication
based simulations, and includes channel coding functions, mobile
propagation
channel models and some mathematical tool needed in communications
engineering and DSP development.

Split-Functionality MAC Protocols (George N.) - We take a
“split-functionality” approach to implementing core MAC functions
between
the host processor and radio hardware to allow high-performance MAC
implementations on high-latency SDRs. We provide basic building blocks
to
build MAC protocols on GNU Radio and the USRP, and provide
implementations
of a CSMA and TDMA MAC protocol from which you can build.

IEEE802.11a/g/p OFDM Frame Encoder (Telecomm. Research Center Vienna
(FTW))

  • This encoder is able to generate and transmit standard-compliant
    IEEE802.11a, IEEE802.11g or IEEE802.11p (draft) frames using the
    GNURadio
    framework. The package consists of python scripts and C++ sourcecode for
    all
    required processing steps. Also included is a reference encoder script
    (to
    be used within MATLAB, in the src/matlab directory) that was written in
    the
    first phase of development of the GNURadio-based encoder.

RFID Reader, Gen 2 (Michael Buettner) - This project implements a Gen 2
RFID
reader capable of inter-operating with commercial tags. To meet the
timing
requirements of the Gen 2 standard, a number of optimizations were
necessary, including modifications to GNU Radio’s USB subsystem. For our
application, we were able to achieve < 300 us system latencies.

George,

I want to thank you, as CGRAN has become a great resource for the whole
community. I know you’ve put in a lot of work running it, and it is
very much appreciated.
