The introduction of cognitive radio enables dynamic spectrum access for higher spectrum utilization, due to its ability of awareness of their environment. However, the introduction of cognitive radio technology brings new challenges to wireless networks security. Due to intelligent nature of the attackers, many of the radio frequency jamming...

This paper proposes a new physical layer approach for stealthy jammer detection in wide-band (WB) cognitive radio networks. We consider a WB which consists of multiple narrow-band sub-bands (SB), which can be occupied by licit signals or jammer. To alleviate the overhead of analog-to-digital conversion (ADC), compressed sensing is applied first...
