I am currently tried to implement TDMA scheme on gnuradio. I found that
openBTS had used the approach but need some hardware modification to get
work with GSM network. In my project, hardware modification has to be
avoided hence openBTS solution might not work for me. At the moment, I
tried to implement some time-stamping method using software as USRP1 is
supported by UHD driver. Has anyone look this matter? Could anyone at
give me an idea where should I start?
