Unambiguous Delay-Doppler Recovery from Random Phase Coded Pulses
Xiang Liu, Deborah Cohen, Tianyao Huang +2
Pulse Doppler radars suffer from range-Doppler ambiguity that translates into a trade-off between maximal unambiguous range and velocity. Several techniques, like the multiple PRFs…
Sub-Nyquist Radar Systems: Temporal, Spectral and Spatial Compression
Deborah Cohen, Yonina C. Eldar
Conventional radar transmits electromagnetic waves towards the targets of interest. In between the outgoing pulses, the radar measures the signal reflected from the targets to dete…
High Resolution FDMA MIMO Radar
David Cohen, Deborah Cohen, Yonina C. Eldar
Traditional multiple input multiple output radars, which transmit orthogonal coded waveforms, suffer from range-azimuth resolution trade-off. In this work, we adopt a frequency div…
Analog to Digital Cognitive Radio: Sampling, Detection and Hardware
Deborah Cohen, Shahar Tsiper, Yonina C. Eldar
The proliferation of wireless communications has recently created a bottleneck in terms of spectrum availability. Motivated by the observation that the root of the spectrum scarcit…
Spectrum Sharing Radar: Coexistence via Xampling
Deborah Cohen, Kumar Vijay Mishra, Yonina C. Eldar
This paper presents a spectrum sharing technology enabling interference-free operation of a surveillance radar and communication transmissions over a common spectrum. A cognitive r…
WINDOW: Wideband Demodulator for Optical Waveforms
Omri Lev, Tal Wiener, Deborah Cohen +1
Optical communication systems, which operate at very high rates, are often limited by the sampling rate bottleneck. The optical wideband regime may exceed analog to digital convert…
SUMMeR: Sub-Nyquist MIMO Radar
David Cohen, Deborah Cohen, Yonina C. Eldar +1
Multiple input multiple output (MIMO) radar exhibits several advantages with respect to traditional radar array systems in terms of flexibility and performance. However, MIMO radar…
CaSCADE: Compressed Carrier and DOA Estimation
Shahar Stein, Or Yair, Deborah Cohen +1
Spectrum sensing and direction of arrival (DOA) estimation have been thoroughly investigated, both separately and as a joint task. Estimating the support of a set of signals and th…
Sub-Nyquist Cyclostationary Detection for Cognitive Radio
Deborah Cohen, Yonina C. Eldar
Cognitive Radio requires efficient and reliable spectrum sensing of wideband signals. In order to cope with the sampling rate bottleneck, new sampling methods have been proposed th…
Sub-Nyquist Sampling for Power Spectrum Sensing in Cognitive Radios: A Unified Approach
Deborah Cohen, Yonina C. Eldar
In light of the ever-increasing demand for new spectral bands and the underutilization of those already allocated, the concept of Cognitive Radio (CR) has emerged. Opportunistic us…
