Flexible Constraint Length Viterbi Decoders On Large Wire-area Interconnection Topologies
(2010-12-30)
To achieve the goal of efficient ”anytime, anywhere” communication, it is essential to develop mobile devices which can efficiently support multiple wireless communication standards. Also, in order to efficiently accommodate ...
A Novel Higher Order Noise Shaping Sigma-Delta Modulator
(2010-06-04)
The thesis focuses on a higher order noise-shaping Δ ADC architecture which employs filtered quantization error as a dither signal. Furthermore, the work studies implementation challenges using Switched-Capacitor and ...
Potential-Based Routing In Wireless Sensor Networks
(2010-07-19)
Recent advances in VLSI technology, and wireless communication have enabled the development of tiny, low-cost sensor nodes that communicate over short distances. These sensor nodes, which consist of sensing, data processing, ...
Joint Congestion Control, Routing And Distributed Link Scheduling In Power Constrained Wireless Mesh Networks
(2010-07-29)
We study the problem of joint congestion control, routing and MAC layer scheduling in multi-hop wireless mesh networks, where the nodes in the network are subjected to energy expenditure rate constraints. As wireless ...
Analytical And Numerical Study Of Propagation In Optical Waveguides And Devices In Linear And Nonlinear Domains
(2010-07-23)
The objective of this thesis is to study of optical effects, arising in the form of non-uniform waveguide structure, complicated refractive index profiles or due to pulse propagation in dense wavelength division multiplexing ...
Low Decoding Complexity Space-Time Block Codes For Point To Point MIMO Systems And Relay Networks
(2010-07-12)
It is well known that communication using multiple antennas provides high data rate and reliability. Coding across space and time is necessary to fully exploit the gains offered by multiple input multiple output (MIMO) ...
Interference Management For Vector Gaussian Multiple Access Channels
(2010-06-03)
In this thesis, we consider a vector Gaussian multiple access channel (MAC) with users demanding reliable communication at specific (Shannon-theoretic) rates. The objective is to assign vectors and powers to these users ...
Providing QoS To Real-time And Data Applications In 3G Wireless Systems
(2010-07-29)
In this thesis we address the problem of providing end-to-end quality of service (QoS) to real-time and data connections in a third generation (3G) cellular network based on the Universal Mobile Telecommunication System ...
Errors In Delay Differentiation In Statistical Multiplexing
(2010-03-03)
Different applications of communication networks have different requirements that depend on the type of application. We consider the problem of differentiating between delay-sensitive applications based on their average ...
Linear Network Coding For Wireline And Wireless Networks
(2010-02-10)
Network Coding is a technique which looks beyond traditional store-and-forward approach followed by routers and switches in communication networks, and as an extension introduces maps termed as ‘local encoding kernels’ and ...
