Design And Analysis Of Microstrip Ring Antennas For Multi-frequency Operations
(2013-06-18)
In this research we attempted several modifications to microstrip ring/loop antennas to design multi-frequency antennas through systematic approaches. Such multi-frequency antennas can be useful while building compact ...
Low Power Receiver Architecture And Algorithms For Low Data Rate Wireless Personal Area Networks
(2013-09-03)
Sensor nodes in a sensor network is power constrained. Transceiver electronics of a node in sensor network consume a good share of total power consumed in the node. The thesis proposes receiver architecture and algorithms ...
Statistical Leakage Analysis Framework Using Artificial Neural Networks Considering Process And Environmental Variations
(2013-07-03)
Leakage current and process variations are two primary hurdles in modern VLSI design. It depends exponentially on process and environmental parameters and hence small variations in these result in a large spread in leakage ...
Performance Analysis Of Post Detection Integration Techniques In The Presence Of Model Uncertainties
(2013-07-10)
In this thesis, we analyze the performance of the Post Detection Integration (PDI) techniques used for detection of weak DS/CDMA signals in the presence of uncertainty in the frequency, noise variance and data bits. Such ...
Optimum Event Detection In Wireless Sensor Networks
(2013-06-12)
We investigate sequential event detection problems arising in Wireless Sensor Networks (WSNs). A number of battery–powered sensor nodes of the same sensing modality are deployed in a region of interest(ROI). By an event ...
Device Structure And Material Exploration For Nanoscale Transistor
(2013-07-03)
There is a compelling need to explore different material options as well as device structures to facilitate smooth transistor scaling for higher speed, higher density and lower power. The enormous potential of nanoelectronics, ...
Robust Precoder And Transceiver Optimization In Multiuser Multi-Antenna Systems
(2013-10-04)
The research reported in this thesis is concerned with robust precoder and transceiver optimization in multiuser multi-antenna wireless communication systems in the presence of imperfect channel state information(CSI). ...
Cooperative Communication In Store And Forward Wireless Networks Using Rateless Codes
(2013-08-30)
In this thesis, we consider a cooperative relay-assisted communication system that uses rateless codes. When multiple relays are present, the relay with the highest channel gain to the source is the first to successfully ...
On The Fourier Transform Approach To Quantum Error Control
(2013-10-07)
Quantum mechanics is the physics of the very small. Quantum computers are devices that utilize the power of quantum mechanics for their computational primitives. Associated to each quantum system is an abstract space known ...
