GSoC 2014 project "Wireless Networks In-the-Loop" and "Channel Sounder"

Hi everyone,

My name is Achuth PV, first year Master of Technology student in
Communication and Signal Processing, Indian Institute of Technology,
Bombay, India.

I am really interested to work in the GSoC project “Wireless Networks
In-the-Loop” and “Channel Sounder”( proposed in 2012 ).

=============================

Wireless Networks In-the-Loop

The basic idea behind “Wireless Networks In-the-Loop” (WiNeLo) is to
build
a GR-based network emulator. This implies the modeling of the underlying
SDR hardware, the individual channels & interference characteristics, as
well as the timing behavior (produce correct amount of noise samples if
no
node is transmitting). The project already started in 2011 and as a
outcome, the basic functionality – the framework with client-server
based
“sample dispatcher” as well as some example hardware & channel models –
has already been implemented in the gr-winelo OOT, which will be
published
on github soon. See
http://video.fosdem.org/2014/AW1125/Sunday/Wireless_Networks_IntheLoop.webm
for
a quick introdcution to “Wireless Networks In-the-Loop”.
ObjectivesThere are various tasks covering several areas. Possible
(sub-)projects are:

  • (Signal Processing) Implementation of new hardware/channel models
    like
    a SDR platform/specific daughterboards or reference channels.
  • (Optimization & Performance) Improve performance of existing
    implementation (port python code to C/C++, develop new mechanisms to
    collect & distribute samples between several nodes).
  • (Signal Processing & Development Tools) Implementation of new
    development tools like “breakpoints on the air link” (pause the
    entire
    emulation if certain criteria (BER, SNR, interference/collisions) is
    fulfilled on the virtual channel/at single nodes).

Channel Sounder (Proposed in 2012)

Details: Channel sounding describes the process of measuring a
multipath
propagation channel and obtain information about excess delay, Doppler
spread and fading properties. The final product should make use of USRPs
for channel sounding (the high timing constraints require use of the
FPGA)
and provide a complete measurement tool which can be used to gather
statistics about mobile communication channels.
Knowledge prerequisite: Digital signal processing basics, FPGA basics
Access to USRPs required.

=========================

My fields of interest are signal processing, wireless and digital
communication, hardware and software programming and data networks.

I am really comfortable in programming using C/C++, java, matlab,
assembly
language, VHDL and I have understanding of Python, CUDA, git. I am also
comfortable in working in Linux. I am a team player and a fast learner
and
has got good commitment. My B Tech final year project was
“Implementation
and comparison of various DCT architectures on FPGA using VHDL”

I got exposed to GnuRadio for the first time as a part of a course
project
in Wireless and Mobile Communication taken as a part of my masters.

I want to contribute a lot to the open source world and I want GSoC to
be
the stepping stone for that.

Can any one please tell me how to start working on these projects.

Thanks in Advance

Hi Achuth,

Channel sounding with USRP radios and GNU Radio has been done by some
folks
at Rutgers and AT&T Labs.

http://arxiv.org/pdf/1211.4940v1.pdf

It might be a good idea to contact Nazmul I. (CCed) about this
project.
Good luck.

best,
aditya

Thanks Aditya

Achuth, Aditya,

channel sounding is not really what this project is about (although it’s
a small part, sure).

I recommend you watch the FOSDEM video and read the papers, then come
back with specific questions.

Hi every one,

I have certain doubts regarding the “Wireless networks in the loop”
project.
The optimization part which is suggested as one of the possible sub
projects- is the plan to move the python code to c++ so as to use the
VOLK
libraries.
Which SDR board / daughter board is initially planned to implement.
I would also like to know more about the client-server as well as about
the
server used.

Can any one please guide me regarding this project so that I can set up
proper goals for the proposal.

Thanks in Advance

Hi everyone,

Following is the link to the my GSOC proposal for the project “Wireless
Networks in-the-loop”.
I am looking forward to feedback on the proposal.

In order to obtain some quick feedback before the submission process
ends, I recommend to post your proposal in google melange…
