Spatial modulation (SM) is a relatively new and attractive modulation technique for multi-antenna wireless systems. In SM, only one among ns = 2m available transmit antennas, chosen on the basis of m information bits, is ...

The general theme of this thesis is modeling, performance analysis, and design of wireless networks under standardized CSMA/CA MAC protocols. In particular, we consider two widely used MAC protocols, namely, IEEE 802.15.4, ...

Solution of Maxwell's equations is required to model and analyse electromagnetic behaviour of circuits, components and systems. These equations being partial differ finial equations of vector field quantities with spatial ...

Current and next generation wireless cellular systems strive to maximize spectral efficiency and meet the increasing demand for higher data rates despite being severely constrained by the limited availability of spectrum. ...

Signals generated by fast moving acoustic sources are both challenging for analysis as well as rich in information. The motion is conceptually relative between the source and receiver i.e., either one of them is moving or ...

The inception of ubiquitous computing goes back to late eighties, when the Research at the Xerox Palo Alto Research (PARC) started designing ubiquitous environment under the guidance of Mark Weiser. Ubiquitous computing ...

ABSTRACT In the modern day , we are witnessing two complementary trends, exponential growth in data and shrinking of chip size. The Data is approaching to 44 zettabytes by 2020 and the chips are now available with 10nm ...

Microring resonators have rapidly emerged in the past few years as a new sensing platform for miniaturization of modern integrated optical devices. Ring resonator are having advantages of compactness, stability with ...

Given the breath-taking pace at which the amount of data being generated on a daily basis is growing, and the keen desire to extract information from this data, there is strong interest within the storage industry, at ...

Opportunistic selection reaps the benefits of multiuser diversity in many wireless applications. For example, it increases throughput of cellular networks, lifetime of wireless sensor networks, and improves diversity in ...
