Optimizing the UE Transmission Probability for D2D Direct Discovery

December 5, 2016
Author(s)
David W. Griffith, Fiona Z. Lyons
We develop an analytical model to examine the effect of the transmission probability on type~1 direct discovery in Device-to-Device (D2D) Long Term Evolution (LTE) networks. The model gives us the distribution of the time for a User Equipment (UE) to

Pathloss Models for Indoor Hotspot Deployment at 83.5 GHz

December 3, 2016
Author(s)
Camillo Gentile, Jelena Senic, Peter B. Papazian, Jae-Kark Choi, Kate Remley
Conventional pathloss models are based on the received power from an omnidirectional antenna. Millimeter-wave receivers, conversely, will feature highly directional antennas that can be steered towards the angle with maximum power, exploiting their high

BLER Performance Evaluation of LTE Device-to-Device Communications

November 9, 2016
Author(s)
Jian Wang, Richard A. Rouil
Long-Term Evolution (LTE) supporting Device-to-Device (D2D) communication is a feature introduced in 3rd Generation Partnership Project (3GPP) release 12. D2D communication is critical in public safety applications, which enables communication among first

A Tetherless, Absolute-Time Channel Sounder, Processing, and Results for a Complex Environment

November 4, 2016
Author(s)
David R. Novotny, Alexandra E. Curtin, Catherine A. Remley, Peter B. Papazian, Jeanne T. Quimby, Richard Candell
we present a channel sounder that can operate without a tether and still maintain an absolute time reference between the source and receiver. Based on a sliding correlator, with synchronized rubidium clocks to generate phase references for the up- and down

A Clustering-Based Device-to-Device Communication to Support Diverse Applications

October 13, 2016
Author(s)
Amirshahram Hematian, Wei Yu, Chao Lu, David W. Griffith, Nada T. Golmie
The expanding coverage and capacity of cellular networks through broadband wireless infrastructure has limitations in accommodating the expanding strain and capacity required by diverse applications (public safety, smart grid, transportation, healthcare

Using Absorption Cross Section to Predict Coherence Bandwidth and other Characteristics of a Reverberation Chamber Set-up for Wireless System Tests

October 3, 2016
Author(s)
Catherine A. Remley, Jos Dortmans, Damir Senic, Chih-Ming Wang, Christopher L. Holloway
We present a method to predict the coherence bandwidth, delay spread and power transfer function of a reverberation chamber set-up. The method is based on the absorption cross section of the absorbing material that is added to the chamber. With an S

Ultra-Dense Networks: Survey of State of the Art and Future Directions

August 4, 2016
Author(s)
Wei Yu, Hansong Xu, Hanlin Zhang, David W. Griffith, Nada T. Golmie
Abstract—Within the foreseeable future, the growing number of mobile devices, and their diversity, will challenge the current network architecture. Furthermore, users expect higher data rates, lower latency, lower packet drop rates, etc. in future wireless
