Topics in Network Utility Maximization : Interior Point and Finite-step Methods
(2018-03-12)
Network utility maximization has emerged as a powerful tool in studying flow control, resource allocation and other cross-layer optimization problems. In this work, we study a flow control problem in the optimization ...
Modelling and Performance Analysis of New Coolstreaming for P2P IPTV
(2018-02-23)
Peer to peer networks are becoming increasingly popular among Internet users as the downloading peers share the storage and upload bandwidth load of the system. This makes it possible for a large number of users to share ...
Analysis and Optimization of Cooperative Amplify-and-Forward Relaying with Imperfect Channel Estimates
(2018-03-17)
Relay-based cooperation promises significant gains in a wireless network as it provides an inde-pendent path between a source and a destination. Using simple single antenna nodes, it exploits the spatial diversity provided ...
Delay Minimization of an M/M/1 Point-to-Point Link Model Subject to Throughput and Power Constraints
(2018-02-15)
In this thesis, we address the problem of minimizing the average delay of data pack-ets served by a transmitter on a static, point-to-point link. The transmitter dynamically chooses state-dependent admission and transmission ...
Generalized Analytic Signal Construction and Modulation Analysis
(2018-04-02)
This thesis deals with generalizations of the analytic signal (AS) construction proposed by Gabor. Functional extensions of the fractional Hilbert Transform (FrHT) are proposed using which families of analytic signals are ...
Sparse Bayesian Learning For Joint Channel Estimation Data Detection In OFDM Systems
(2018-08-30)
Bayesian approaches for sparse signal recovery have enjoyed a long-standing history in signal processing and machine learning literature. Among the Bayesian techniques, the expectation maximization based Sparse Bayesian ...
Design, Analysis and Development of Sensor Coil for Fiber Optics Gyroscope
(2018-07-30)
Interferometer Fiber Optic Gyroscope (IFOG) has established as critical sensor for advance navigation systems. Sensor coil is known to be heart of IFOG. The bias drift and scale factor performance of IFOG depend on the ...
