Opportunistic spectrum access with temporal-spatial reuse in cognitive radio networks

ICASSP 2016accepted

We formulate and study a multi-user multi-armed bandit (MAB) problem that exploits the temporal-spatial reuse of primary user (PU) channels so that secondary users (SUs) who do not interfere with each other can make use of the same PU channel. We first propose a centralized channel allocation policy…

Detection of pilot spoofing attack in multi-antenna systems via energy-ratio comparison

ICASSP 2015accepted

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 att…
