Design and characteristic analysis of hybrid OFD–LFM–PC waveforms in the MIMO radar
The Journal of Engineering, 2019 In this study, a new set of hybrid orthogonal frequency division–linear frequency modulation–phase coded (OFD–LFM–PC) waveforms are proposed to improve the detection performance of multiple-input-multiple-output (MIMO) radars.

On the Security of Cognitive Radio Networks [PDF]
IEEE Transactions on Vehicular Technology, 2015 Cognitive radio has emerged as an essential recipe for future high-capacity, high-coverage multitier hierarchical networks. Securing data transmission in these networks is of the utmost importance. In this paper, we consider the cognitive wiretap channel and propose multiple antennas to secure the transmission at the physical layer, where the ...
