Subject: Re: [Discuss-gnuradio] new 802.11b receiver
Mohammad:
Do you know Fehrouz Farhang-B? I am sure you must. He is an
acquaintance of mine. Are you in the Wireless Communications Lab or the
DSP Lab (Signal Processing Group)?
I have before, and I wish to recommend again, Fehrouz book on SDR
techniques to people here.
http://www2.elen.utah.edu/~farhang/Who is directing your thesis work? I want to remind you and everyone
else listening, that we will soon have the USRP2. It will definitely
support the 802.11b and
g. It would be good to have the code early so
we can make a plan on moving it to the USRP2 to support the full bandwidth.
I am looking forward to visit your department at some time in the next
few months. I hope to be able to meet you.
Thank your for doing this work!

definition, not smart enough to debug it." - Brian W. Kernighan
