Forum: GNU Radio GNUradio based papers on channel sounding and TDMA

Hello,

I would like to announce two GNUradio based papers that I
published/submitted a few months ago. The full reference of the papers 
are
given below:

1. Muhammad Nazmul Islam, Byoung-Jo J. Kim, Paul Henry, Eric Rozner, "A
Wireless Channel Sounding System for Rapid Propagation
Measurements<http://arxiv.org/abs/1211.4940>",
submitted to International Conference on Communications 2013. (
http://arxiv.org/abs/1211.4940)

2. Muhammad Nazmul Islam, Shantharam Balasubramanian, Narayan B. 
Mandayam,
Ivan Seskar, Sastry Kompella, "Implementation of Distributed Time 
Exchange
Based Cooperative Forwarding <http://arxiv.org/abs/1210.5424>", 
published
in Military Communications Conference 2012
(http://arxiv.org/abs/1210.5424)

I also want to address a particular point about my channel sounding
experiments. I have seen several channel sounding based posts in the
mailing list where the authors talk about the speed bottlenecks of 
Gigabit
ethernet cable. Basically, the speed bottleneck of the ethernet cable or
the computer limits the temporal resolution of the sliding correlator 
based
channel sounding. For example, if you transmit at 10 Mega Symbol/sec, 
you
can only find multipath components at 100 ns, 200 ns, etc. However, this
problem can be bypassed by using frequency domain channel sounding. One 
can
send a frequency hopping sequence, determine the frequency domain 
channel
characteristics and then find the channel impulse response through 
inverse
FFT. In this case, the temporal resolution of the multipath components
won't depend on the symbol rate. The paper #1 talks about both sliding
correlator and frequency domain channel sounding approaches.

I took the opportunity to add a copy on the academic papers section:
http://gnuradio.org/redmine/projects/gnuradio/wiki....
Feedback and comments will be very appreciated.

Thanks,

Nazmul

Hi Nazmul,

I just wanted to say thanks for posting this and keeping the paper 
section
of the Wiki up to date. Looks like some great stuff!

Hi,
Recently my paper "*A Low-cost and Flexible Underwater Platform to 
Promote *
*Experiments in UWSN Research*" has been accepted in WUWNET'12
conference,held on Nov 5th, 6th at Los Angeles , California ,USA.

We have implemented our modem using GNURadio.The codes can be accessed 
at
http://sysnet.org.pk/w/Code_and_Tools.
I am unable to upload the paper in the Academic Paper section. I wish if
someone help me in uploading.

Hi Niaz,

this should explain how you log on:
http://gnuradio.org/redmine/projects/gnuradio/wiki...

You can use the guest:gnuradio access if you don't like to log on.

Thanks for using GNU Radio and contributing to the website,
MB

Hi Nazmul,

Seem your second paper can not downloadable?

Thanks

Alex,
*Dreams can come true  just believe.*

Hi,Martin,
I have created a GNURadio account and now wish to upload my paper in the
academic section. I wish to be added as contributor so that I may upload 
in
the academic section.I put an email to Tom Rondeau but I guess he might 
be
busy right now doing other stuff.

Hi Niaz,

1. Go to GNUradio webpage

2. Sign in to your account

3. Go to GNUradio academic papers sections/page

4. There should be an option called "Edit". Use it to include your 
paper.

Thanks,

Nazmul

Niaz,

I set you up with edit privileges when you asked me a couple of days 
ago.
Either I forgot to email you back (most likely) or the email never made 
it
(probably not). Anyways, you're all set to update the wiki.

Tom
