Opportunistic unlicensed access to the (tem- porarily) unused frequency bands across the licensed radio spectrum is currently being inves- tigated as a means to increase the efficiency of spectrum usage. Such opportunistic access calls for implement
mobile networks will become programmable! migration paths to new technologies needed e.g., software radios create wireless physical layers dynamically we extend programmability to the signaling plane and MAC layer

Power scaling for cognitive radio In this paper we explore the idea of using cognitive radios to reuse locally unused spectrum for their own transmissions.
Absolutely terrific book about superhet (and other styles) of radio design. It's like sitting at the bench with the author and watching him put them together, discussing why he made the choices that he did. He even goes a little bit into SDR (softwa
