Precoding and Channel Estimation Schemes for MIMO VLC Systems
Increase in the usage of smartphones and growing demand for data have resulted in
congestion in the RF spectrum. To ease the overcrowding of RF spectrum, there is a
need for wireless communication systems that can ...
Low Power Analog Neural Network Framework with MIFGMOS
Ever since the beginning of the notion behind the term 'cloud computing,' i.e., to share the pro-
cessing and storage capabilities of a centralized system, there has been a signi cant increase in the
availability of raw ...
Pitch-Synchronous Discrete Cosine Transform Features for Speaker Recognition and Other Applications
Extracting speaker-speci c information from the speech is of great interest since speaker recognition
technology nds application in a wide range of areas such as forensics and biometric
security systems. In this thesis, ...
Spectral Efficiency Improvement in Spatial Modulation Systems
A novel energy efficient Multiple-Input-Multiple-Output (MIMO) technique is called Spatial Mod-
ulation (SM). It uses only one radio frequency (RF) chain that reduces the hardware complexity
and cost of the system. The ...
Transmit Antenna Selection in Underlay Spectrum Sharing: Role of Power Adaptation, Interference Constraint, and Channel State Information
Spectrum sharing is essential to support high wireless data rates and a large number of wireless connections by the future technologies in the limited spectrum that is available. In underlay spectrum sharing a secondary ...
First Principles Based Mobility Estimation of Graphene
Electron-phonon coupling (EPC) plays a vital role in detecting transport properties
(e.g. mobility) of any material. First principles-based estimation of the
mobility for any new material could act as a useful guideline ...
Design of Authentication and Privacy Schemes for a Generic Social Network
In social networks, people (also known as actors) are often connected to each other in order to share the
information. With the advancement in the information technology, social networks have in
influenced actors
of ...
Atom-to-circuit Modeling Strategy for 2d Transistors
Two-dimensional materials are now being considered as viable options for CMOS (complementary metal-oxide-semiconductor) technology extension due to their diverse electronic and opto-electronic properties. However, introduction ...
A Fast Constant-Time Approximation for Locally Adaptive Bilateral Filtering
Smoothing is a fundamental task in low-level image processing that is used to suppress irrelevant
details while preserving salient image structures. The simplest smoothing mechanism is
to average neighboring pixels using ...
Differential Encoding for Real-Time Status Updates
We consider the problem of status updates of a physical process over an unreliable channel. In
this setting, one may not be able to reliably transmit the current state at all times. Instead, one
is interested in the ...
