The Time-Division mode for Long Term Evolution (TD-LTE) is viewed by many as the first waveform that will be enabled by Dynamic Spectrum Access (DSA) and see widespread adoption in both the commercial and public safety arena. The Third Generation Partnership Project (3GPP) is developing standards for DSA-enabling TD-LTE. In this paper we take an initial(More)
—This paper explores an overlapped-multiple-input multiple-output (MIMO) antenna architecture and a spectrum sharing algorithm via null space projection (NSP) for radar-communications coexistence. In the overlapped-MIMO architecture , the transmit array of a collocated MIMO radar is partitioned into a number of subarrays that are allowed to overlap. Each of(More)
This paper presents a new concept of device fingerprinting (or profiling) to enhance wireless security using Infinite Hidden Markov Random Field (iHMRF). Wireless device fingerprinting is an emerging approach for detecting spoofing attacks in wireless network. Existing methods utilize either time-independent features or time-dependent features, but not both(More)
—With the now widespread availability of software defined radio technology for wireless networks, the distinction between jamming in the original electronic warfare sense and wireless cyber security attacks becomes hazy. In order to delineate these concepts in the rapidly expanding field of wireless security, we propose a jammer taxonomy to classify the(More)
