We study a spoofing attack happened in the physical layer of a multiple-antenna system, where an adversary tries to spoof the transmitter by sending the identical pilot (training) signal as that of a legitimate receiver in the uplink channel estimation phase. This attack, named as pilot spoofing attack, could lead to a secrecy information leakage to the adversary and information rate decrease at the...
Opportunistic spectrum access (OSA) is a key technique for the secondary user (SU) in a Cognitive Radio network to transmit over the "spectrum holes" unoccupied by the primary user (PU). Most existing work on the design of OSA has assumed a non-reactive (NR) PU model, i.e., the PU transmission on-off status is independent of the SU access policy, which may not be practical. In this paper,...
Food requires strict temperature control throughout the so-called 'cold-China', in which a particular storage temperature is need for each link. Display cabinets are known to be the weakest link from this point of view and, therefore, particular attention is paid to their design. And it is a real challenge for manufacturers and users of refrigerated display cabinets to provide the products with minimal...
