3D Beam-Steering MIMO Antenna for On-Body IoT Applications
(IEEE, 2023)In this article, a compact 3D beam-steering MIMO antenna operating at 5.75 GHz is proposed for on-body Internet of Things (IoT) applications. The planar antenna comprises a central patch and two concentric annular rings. ... -
Adaptation in a Channel Access Game with Private Monitoring
(2013)Under the opportunistic spectrum access paradigm, the shared pool of spectrum bands that the multiple autonomous cognitive radios (CRs) need to compete for is not necessarily homogeneous. The non-homogeneity in channels ... -
An Analysis of Competition among Autonomous Devices in Multichannel Cognitive Radio Networks
(2012)We investigate an autonomous opportunistic spec- trum access (OSA) strategy for a multichannel cognitive radio (CR) network, where two or more autonomous CRs sense the channels sequentially in some sensing order to find ... -
Artificial Intelligence for Dynamical Systems in Wireless Communications: Modeling for the Future
(2021)Dynamical systems are no strangers in wireless communications. Our story will necessarily involve chaos, but not in the terms secure chaotic communications have introduced it: we will look for the chaos, complexity and ... -
Attention-based audio-visual fusion for robust automatic speech recognition
(2018)Automatic speech recognition can potentially benefit from the lip motion patterns, complementing acoustic speech to improve the overall recognition performance, particularly in noise. In this paper we propose an audio-visual ... -
Biaxial order and a rotation of the minor director in the nematic phase of an organo-siloxane tetrapode by the electric field
(2012)Biaxiality in the nematic phase for a liquid crystalline tetrapode made up of organo-siloxanes mesogens is investigated using polarized infrared spectroscopy. An ordering of the minor director for the homeotropically aligned ... -
Biaxial order parameter in the homologous series of orthogonal bent-core smectic liquid crystals
(2013)The fundamental parameter of the uniaxial liquid crystalline state that governs nearly all of its physical properties is the primary orientational order parameter (S) for the long axes of molecules with respect to the ... -
Blotch and scratch removal in archived film using a semi-transparent corruption model and a ground-truth generation technique
(2013)This paper has two main contributions. The first is a Bayesian framework for removing two common types of degradations on video known as blotches and line scratches. Most removal techniques assume complete obliteration of ... -
Carrier Aggregation as a Repeated Game: Learning Algorithms for Efficient Convergence to a Nash Equilibrium
(2013)Carrier aggregation is a key feature of next generation wireless networks to deliver high-bandwidth links. This paper studies carrier aggregation for au- tonomous networks operating in shared spectrum. In our model, ... -
A Combinatorial Optimisation Approach to the Design of Dual Parented Long-Reach Passive Optical Networks
(2011)We present an application focused on the design of resilient long-reach passive optical networks. We specifically consider dual-parented networks whereby each customer must be connected to two metro sites via local exchange ...
