We present a near field wireless power transfer (NF-WPT) link which is also capable of datacommunication through complex, quadrature amplitude (QAM) load modulation. We present a method for designing a 4QAM constellation that allows for minimal degradation of the NF-WPT link efficiency by minimizing the complex reflection coefficient. Using a modulation board and a resonant 4-coil…

Interrelationship of protection and communication to improve power system reliability
Dependencies of protection schemes on communications have been acknowledged and discussed in various papers. This paper expands this topic by examining field experiences that required protection engineers to deepen their understanding of communication technologies to interpret protection scheme behavior and perform event analysis. A deployed power system line protection application utilizing segregated phase comparison protection scheme with distance protection…
Semi-Persistent RRC Protocol for Machine-Type Communication Devices in LTE Networks
In this paper, we investigate the design of a radio resource control (RRC) protocol in the framework of long-term evolution (LTE) of the 3rd Generation Partnership Project regarding provision of low cost/complexity and low energy consumption machine-type communication (MTC), which is an enabling technology for the emerging paradigm of the Internet of Things. Due to the nature…
Evaluating the Performance Impact of Communication Imbalance in Sparse Matrix-Vector Multiplication
HPC applications make intensive use of large sparse matrices with the matrix-vector product representing a significant fraction of the total run-time. These matrices are characterized by non-uniform matrix structures and irregular memory accesses that make it difficult to achieve a good scalability in modern HPC platforms with multi-or many-cores, SIMD and high-speed communication networks. One of the…
LED Based Indoor Visible Light Communications: State of the Art
Visible Light Communication (VLC) is an emerging eld in Optical Wireless Com- munication (OWC) which utilizes the superior modulation bandwidth of Light Emitting Diodes (LEDs) to transmit data. In modern day communication systems, the most pop- ular frequency band is Radio Frequency (RF) mainly due to little interference and good coverage. However, the rapidly dwindling RF spectrum along with…
A Touch-Communication Framework for Drug Delivery Based on a Transient Microbot System
Recent progress in bioresorbable radio frequency electronics and engineered bacteria has promised the prospect of realizing a transient microbot (TM) system for therapeutic applications. The inorganic or organic miniature robots will dissolve into the human body after completing the required tasks and cause no side-effect. In this paper, we propose a potential architecture of a…
On the Nanoscale Electromechanical Wireless Communication in the VHF Band
Electromagnetic communication at the nanoscale has, to date, been studied in either the very high frequency (VHF) (30-300 MHz) or in the TeraHertz band (0.1-10 THz). The main focus of this paper is on electromagnetic communication in the VHF band and determining the bit error rate (BER) performance of nanoscale receivers utilizing a carbon nanotube (CNT). To determine BER…
Exploring the Impact of Social Communication on the Innovation Potential of Open Science Communities
As scientific communities become increasingly complex and interdisciplinary, implementing policies that foster collective creativity for science-based innovation emerges as a critical issue. In this paper, we investigate the impact of socio-communication strategies on innovation capacity based on experiments using a general-purpose model that aims to study dynamic processes of collective creativity in scientific communities. Experimental results…
10.2 An FSK plastic waveguide communication link in 40nm CMOS
Technology scaling has enabled RF-CMOS circuits that operate in the millimeter-wave frequency range (30 to 300GHz) where large bandwidths are available. These bandwidths can be exploited to increase data-rates of wireless communication links. Unfortunately, free-space path loss (FSPL) limits the operating distance of wireless systems at these frequencies. A 5-meter link at 120GHz has an FSPL as…
Diffusion-Based Clock Synchronization for Molecular Communication Under Inverse Gaussian Distribution
Nanonetworks are expected to expand the capabilities of individual nanomachines by allowing them to cooperate and share information by molecular communication. The information molecules are released by the transmitter nanomachine and diffuse across the aqueous channel as a Brownian motion holding the feature of a strong random movement with a large propagation delay. In order to…
