Dynamic Sparse Subspace Clustering for Evolving High-Dimensional Data Streams
In an era of ubiquitous large-scale evolving data streams, data stream clustering (DSC) has received lots of attention because the scale of […]
Arithmetic Tracking Adaptive SAR ADC for Signals with Low-activity Periods
This paper introduces a novel arithmetic tracking algorithm for successive approximation ADCs, and presents its analysis. The algorithm utilizes low activity signal […]
Ultra-Low Latency, Low Energy, and Massiveness in the 6G Era via Efficient CSIT-Limited Scheme
Channel state information (CSI) has been a key component in traditional wireless communication systems. This might no longer hold in future networks […]
Digital Timing Error Calibration of Time-Interleaved ADC with Low Sample Rate
This work suggests a novel procedure of calibrating timing mismatch of time-interleaved Analog-to-Digital conversion. Here, the timing mismatch calibration and compensation are […]
A Voltage Controlled Oscillator with Inductive Divider Design and Analysis at Frequencies Above 100 GHz
Millimeter wave oscillators are of particular interest towards future communications and sensing as frequency multiplication of local oscillator signal is resulting in […]
THz Radio Communication
How well do upper millimeter-wave and terahertz frequency bands enable wireless communications? In this work, we approximate the current and estimate the […]
Vegetation height estimation using ubiquitous foot-based wearable platform
Vegetation height plays a key role in many environmental applications such as landscape characterization, conservation planning and disaster management, and biodiversity assessment […]
User Clustering for MIMO NOMA via Classifier Chains and Gradient-Boosting Decision Trees
In this article, we propose a data-driven approach to group users in a Non-Orthogonal Multiple Access (NOMA) MIMO setting. Specifically, we formulate […]
Two-Step Random Access for 5G System
The 3rd Generation Partnership Project (3GPP) finalized Release 15 specifications for the 5th Generation New Radio (5G NR) in June 2018. In […]
Preferential Engagement and What Can We Learn from Online Chess?
An online game of chess against a human opponent appears to be indistinguishable from a game against a machine: both happen on […]
