Performance evaluation and design for communication networks of the future is conducted. Emphasis is placed on large, high-speed networks. Both optical and electronic networks are considered.
Analysis consists of a mixture of exact probabilistic and combinatorial methods and simulation.
Design is motivated by modeling and analysis and aided by optimization tools of both combinatorial and nonlinear iterative types. The goal of this research is to investigate basic issues involved in providing multimedia communications over a heterogeneous network of both wireless and wireline links. This research project seeks to develop robust but near-optimal methods for timing acquisition and demodulation for wireless environments. Multiuser and single-user settings and narrowband and wideband interference are considered in the design and performance evaluation of different receiver structures. This project is an exploration of fundamental problems arising from wireless applications, including topics ranging from transceiver design for multiuser communications to design principles for heterogeneous networks with both wireless and wireline links.
