Dynamic spectrum access in DTV whitespaces: design rules, architecture and algorithms
In November 2008, the FCC ruled that the digital TV whitespaces be used for unlicensed access. This is an exciting development because DTV whitespaces are in the low frequency ran...

Interference management via rate splitting and HARQ over time-varying fading channels
The coexistence of two unlicensed links is considered, where one link interferes with the transmission of the other, over a timevarying, block-fading channel. In the absence of fa...
