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 Islam (CCed) about this project. Good luck. best, aditya On Mon, Mar 3, 2014 at 3:05 PM, achuth pv <achut...@gmail.com> wrote: > 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.
