The hallmark of the information age is the ease with which information is stored, accessed, and shared throughout the globe. This is enabled, in large part, by the simplicity of duplicating digital information without error. Unfortunately, an ever-gr

We propose a method for covert communications using an IEEE 802.11 OFDM/QAM packet as a carrier. We show how to hide the covert message so that the transmitted signal does not violate the spectral mask specified by the standard, and we determine its

We develop a channel estimation approach utilizing the joint sparsity in the virtual channel for OFDM channel estimation in a frequency selective millimeter wave channel. Our approach addresses possible non-uniformly spaced base station antenna array

Wireless devices are ubiquitous and consequently the spectrum is congested. Dynamic spectrum access is becoming more widespread in unlicensed bands and as a means to allow secondary users white space in licensed bands. Spectrum sensing capabilities a

We demonstrate the first integrated photonic physical unclonable function in CMOS compatible highly nonlinear hydrogenated amorphous silicon. We characterize the unclonability of our devices using spectrally-encoded optical pulses for challenge-respo

Under sparse channel assumptions, channel state information for the massive MIMO uplink can be effectively estimated without sampling every antenna. Assuming a slow flat fading multipath channel, orthogonal pilot signals, and a uniform rectangular ar

We demonstrate the unclonability of an integrated photonic chaotic micro-cavity using highly nonlinear hydrogenated amorphous silicon (a-Si:H) as the material platform. Spectrally encoded ultrafast pulses are used to characterize the uniqueness of ou
