Some contributions to asymmetric error control codes

Creator:: Elmougy, Samir
Abstract:: In some practical systems, most of the errors are of 1 → 0 type and 0 → 1 errors occur very rarely. In this thesis, first, the capacity of the asymmetric channel is derived. The capacity of the binary symmetric channel (BSC) and the Z-channel can be derived from this...

One-to-many node disjoint paths routing in generalized hypercube, dense Gaussian, and hexagonal mesh networks

Creator:: Alsaleh, Omar I.
Abstract:: Routing from a single source node to multiple destination nodes using node disjoint paths (NDP) has many important applications in parallel systems. For example, if a source node wants to send distinct messages to distinct destination nodes, then the one-to-many NDP routing is useful. Unlike parallel systems with shared-memory, each...

Coordinating secondary-user behaviors for inelastic traffic reward maximization in large-scale DSA networks

Creator:: NoroozOliaee, MohammadJavad
Abstract:: We develop efficient coordination techniques that support inelastic traffic in large-scale distributed dynamic spectrum access DSA networks. By means of any learning algorithm, the proposed techniques enable DSA users to locate and exploit spectrum opportunities effectively, thereby increasing their achieved throughput (or "rewards" to be more general). Basically, learning algorithms...

Low-power dynamic CMOS circuits in high-performance memory arrays

Creator:: Patwary, Md. Ataur R.
Abstract:: Dynamic CMOS circuits are commonly used in high-performance memory arrays to implement wide-NOR logic functions for their read and search operations. This is because dynamic circuits have significantly higher speed and lower area compared to static circuits for performing similar operations. Register File (RF) arrays are located at the top...

Low-complexity high-speed VLSI design of low-density parity-check decoders

Creator:: Cui, Zhiqiang
Abstract:: Low-Density Parity-check (LDPC) codes have attracted considerable attention due to their capacity approaching performance over AWGN channel and highly parallelizable decoding schemes. They have been considered in a variety of industry standards for the next generation communication systems. In general, LDPC codes achieve outstanding performance with large codeword lengths (e.g.,...

Information theoretic approach to quantization and classification for signal processing, communications, and machine learning applications

Creator:: Thuan Nguyen D.
Abstract:: There are five main contributions of this dissertation. The first contribution is new closed-form expressions for channel capacity of a new class of channel matrices. The second contribution is the discovery of the structure for optimal binary quantizer and the associated methods for finding an optimal quantizer that maximizes mutual...

Adaptive Streaming Methods using Dual Protocols and Reinforcement Learning

Creator:: Gatimu, Kevin
Abstract:: The ubiquity of high quality video and proliferation of mobile devices has contributed to an unprecedented rise in video consumption. HTTP, in conjunction with adaptive streaming, has become the de facto mechanism for delivering the vast majority of video as it readily caters to heterogeneous networks and devices. This dissertation...

Variable sampling compensation of networked control systems with delays using neural networks

Creator:: Lopez-Echevarria, Daniel
Abstract:: In networked control systems (NCS) information or packets usually flow from a sensor or a set of sensors to a remotely located controller. Then the controller processes the received information and sends a series of control commands to the actuators through a communication network which could be either wireless or...

EM-MAC : an energy-aware multi-channel medium access control protocol for multi-hop wireless networks

Creator:: Sivanantha, Akhil
Abstract:: The stupendous growth in wireless and mobile devices in the recent years has prompted researchers to look at innovative approaches that enable effective use of the available resources. In this thesis, we propose a medium access control (MAC) protocol, referred to as EM-MAC, that enables wireless devices with multi-channel access...
