Detecting the greedy spectrum occupancy threat in cognitive radio networks
(
IEEE Computer Society
, 2014 , Conference Paper)
Recently, security of cognitive radio (CR) is becoming a severe issue. There is one kind of threat, which we call greedy spectrum occupancy threat (GSOT) in this paper, has long been ignored in previous work. In GSOT, a ...
On I/Q imbalance effects in full-duplex OFDM decode-and-forward relays
(
IEEE
, 2014 , Conference Paper)
We analyze the outage probability of dual-hop full-duplex decode-and-forward relaying for an orthogonal frequency division multiplexing system in the presence of I/Q imbalance. We derive accurate analytical approximations ...
