A Sub 1V 96 μW Fully Operational Digital Hearing Aid Chip With Internal Status Controller
2006 Edition, September 1, 2006 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A low power fully operational digital hearing aid chip is proposed and implemented. The Sigma-Delta ADC adopts the status controller to realize adaptive SNR technique without any external control. To achieve both low power consumption...

A 0.9 V 96 $\mu$ W Fully Operational Digital Hearing Aid Chip
2007 Edition, Volume 42, November 1, 2007 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A 0.9 V 96 muW fully operational low-power digital hearing aid chip is proposed and implemented. An internal status controller is introduced to achieve full operation of the adaptive-SNR analog front end. Dedicated DSP...

SUMMeR: Sub-Nyquist MIMO Radar
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

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 poses new challenges for both hardware design and digital processing. In particular, achieving high...

Ring-Resonator-Based Sub-THz Dielectric Sensor
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This letter presents a design, fabrication, and measurement of a ring-resonator-based subterahertz (sub-THz) dielectric sensor. The sensor consists of a ring-resonator-based notch filter, a sub-THz dielectric waveguide (DWG), and a pair of...

A Cognitive Sub-Nyquist MIMO Radar Prototype
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We present a cognitive prototype that demonstrates a colocated, frequency-division-multiplexed, multiple-input multiple-output (MIMO) radar which implements both temporal and spatial sub-Nyquist sampling. The signal is sampled and recovered via the Xampling framework. Cognition...

A Sub-Nyquist Radar Electronic Surveillance System
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The modulated wideband converter (MWC) is well known for a sub-Nyquist wideband sampling capability based on compressed sensing (CS) theory. In this paper, our goal is to use the MWC as a base to design a sub-Nyquist radar electronic surveillance (ES) system. Our...

Sub-Nyquist Sampling of Multiple Sinusoids
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, we propose new sub-Nyquist sampling schemes for multiple sinusoids, which require fewer number of samples than previous works. Since it is impossible to resolve the frequency ambiguity using a single sub-Nyquist sample sequence, an additional sampling channel is...

Design of Overlapped Sub-Arrays Based on Aperture Reactive Loading
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A novel technique is presented for the design and optimization of waveguide antenna arrays based on overlapping sub-arrays for limited field-of-view applications. Each sub-array consists of one directly-fed antenna element and several passive reactive-loaded elements. The...

Dynamic Similar Sub-Series Selection Method for Time Series Forecasting
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Accumulation of influencing factors during several consecutive time periods makes the variation of target parameters lag behind the variation of their influencing factors. This important phenomenon, known as the cumulative effect, would lead to relatively large forecasting errors. In this paper,...

An improved high-density sub trajectory clustering algorithm
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

TRACLUS algorithm based on partition-and-group framework could not be distinguished the optimal partitioning accurately when the migration of trajectory points on both sides of corridor middle line was greatly offset, and the algorithm was sensitive to the input parameters. According to above...
