Data Mining and Machine Learning; User-Oriented Security: A Multi-Disciplinary Approach The proposed research is an interdisciplinary project, aiming to develop an adaptive cyber-security system that is personally-adjusted to characteristics of a human user. The project is based on the rapidly developing literature on “usable security” which emerged from the realization that system security often depends […] Read More >
High Speed Photonic Digital-To-Analog Conversion
The Technology A novel integrated optical modulator based on a multi-electrode Mach-Zehnder modulator has been developed at Tel-Aviv University. The device has superior performance in terms of linearity, dynamic range and implementation simplicity. These improvements are achieved by utilizing a unique mapping method between the analog input and the digital sequence applied to the device, […] Read More >
Compressive Sensing in Radar Detection
Technology The signal processing in a pulse-Doppler radar is typically based on pulse compression filter and discrete Fourier transform (DFT). Detection, measurement accuracy and good resolution require the transmission of train of pulses, where each pulse is frequency modulated. In some cases, for ambiguity resolution, a few trains of pulses are required. A reasonable assumption […] Read More >

A new equalizer for Intersymbol Interference (ISI) communication channels with single carrier transmission
The Technology A new equalizer for Intersymbol Interference (ISI) communication channels with single carrier transmission. This equalizer, termed “Integer-Forcing” equalizer, allows to simply and effectively combine decision feedback equalization (DFE) with channel coding (error correcting codes). This is done by transmitting codewords from a cyclic code and equalizing the ISI channel into a channel with […] Read More >

The overall scope of the research is in the development of new approaches to actuation and sensing and their implementation in micro devices. In the realm of micro […] Read More >
EFFICIENT PROCESSING OF COMPRESSED COMMUNICATION TRAFFIC
A method for processing communication traffic includes receiving an incoming stream of compressed data conveyed by a sequence of data packets, each containing a respective portion of the compressed data. The respective portion of the compressed data contained in the first packet is stored in a buffer, having a predefined buffer size. Upon receiving a […] Read More >
INFERRING THE PERIODICITY OF DISCRETE SIGNALS
A method for testing a signal comprises obtaining a signal, determining whether the signal has at least one period, measuring that period and providing the measurement as output. A power spectral density estimation can be used for signals having a single period, and an autocorrelation function with slicing can be used in an iterative procedure […] Read More >
Subharmonic Wireless Locking of THz transmitter
A novel method for wireless sub-harmonic locking a radiating free-running VCO single source or phased-array at THz frequenciesNeed and AdvantagesAlthough many significant challenges remain, results suggest that CMOS THz ICs are inevitability. Still, the lack of efficient, high-power (watt-level) sources remains the most conspicuous impediment to further progress. Promising applications for terahertz technology include non-ionizing […] Read More >
Free online web wizard application to assess the amount of nonlinear interference noise generated in fiber-optic communications systems
Nonlinear interference noise (NLIN) is arguably the most important factor limiting the capacity of fiber-optic communication systems. It is customary to classify nonlinear phenomena as either intra-channel, or inter-channel. Intra-channel effects relate to the nonlinear distortions undergone by each of the WDM channels individually (i.e independently of the data transmitted over other WDM channels), whereas […] Read More >
