Application of Visual Simulation in Communication Systems

Behera, Sameer Ranjan and Mohapatra, Ranjeet (2008) Application of Visual Simulation in Communication Systems. BTech thesis.



A communications system is a collection of individual communications networks, transmission systems, relay stations, tributary stations, and data terminal equipment (DTE) usually capable of interconnection and interoperation to form an integrated whole. The components of a communications system serve a common purpose, are technically compatible, use common procedures, respond to controls, and operate in unison. A typical communication link includes, at a minimum, three key elements: a transmitter, a communication medium (or channel), and a receiver. The ability to simulate all three of these elements is required in order to successfully model any end-to-end communication system. In order to achieve this target we have used a simulation software “VisSim” ,or Visual Simulator ,that allows us to use a graphical approach to simulation and modeling. With graphical programming, the diagram is the source code, depicted as an arrangement of nodes connected by wires. Each piece of data flows through the wires, to be consumed by nodes that transform the data mathematically or perform some action such as I/O. The visual simulator allows us to model end-to-end communication systems at the signal or physical level. We use VisSim/ Comm to build both transmitter and receiver models, filters and equalizers, as well as channel models and coding techniques from a first principles perspective, by selecting and connecting predefined blocks. In this project work we simulate a variety of models including analog, digital and mixed mode designs, and quickly simulate their behavior using the VisSim/Comm software and graphical programming.
