<p>Using Moore’s Law, engineers and scientists have ability to place smart and powerful IC devices,</p><p>with increasingly complex systems on a chip (SoC). This thesis describes the technology of rapid</p><p>prototyping in the field of communication systems. Reconfigurable technologies always help in the</p><p>construction of flexible systems (where hardware and software can be changed at any time during its</p><p>execution). With growing developments in the field of communication systems, DSP is now the</p><p>heart of every communication system; engineers are consequently looking for a smart and reliable</p><p>platform to enhance their production to meet future challenges. This thesis presents a DSP-based</p><p>theoretical survey of rapid prototyping in communication systems. An attempt has been made to</p><p>cover every prototype issue in this theoretical survey. The objective is to make an evaluation to</p><p>judge whether it is feasible for practical educational and research purposes. The test design proposed</p><p>in this thesis for the evaluation is a simple DSP-based Correlator.</p><p>Scientists and engineers are looking for a smart system which can provide end results, in order to be</p><p>implemented in practical, real time environments and for research and educational purposes in</p><p>universities.</p><p>Previously we needed to make a hardware PCB for algorithm testing, especially when we had</p><p>complex algorithms which involved a great deal of work, but with the help of this thesis and other</p><p>research projects this area of rapid prototyping we are beginning to make some progress in the right</p><p>direction.</p><p>The tool chain plays a key role for the development in terms of the evaluation of rapid prototyping in</p><p>communication systems. Currently the available methods to design a system require a great deal of</p><p>time and money along with the efforts of many skilled researchers. Rapid prototyping is a shortcut</p><p>with regards to these usual methods with appropriate tools to achieve the goal.</p><p>In this thesis our main focus is on MATLAB, SIMULINK, REAL TIME WORKSHOP and the</p><p>appropriate Texas Instruments products (Code Composer Studio and Target DSP), to achieve</p><p>maximum performance and reduction of development time. The tools which are discussed are</p><p>actively involved in the design process of systems using the rapid prototyping development</p><p>technique. The basic system design is conducted using the model based on the design of tools in</p><p>Math Works software, consisting of MATLAB and SIMULINK using their tool and block sets.</p><p>Using these tools many applications for educational purposes and on a commercial level have been</p><p>implemented [2]. Here a DSP application, an FFT-based (Fast Fourier Transform) Correlator is</p><p>proposed that measures the phase delay of the two transmitted base band signals that are sampled at</p><p>different rates. Four major phases are involved for the purposes of rapid prototyping : 1) - the system</p><p>algorithm is designed and implemented in MATLAB and SIMULINK, 2) – generation of the</p><p>standard ANSI C code for this designed model has been done by using REAL TIME WORK SHOP,</p><p>3)- implementation of this C code on DSP/Microprocessor-based hardware using an interface and</p><p>4)- carrying out a performance evaluation of this tool chain, i.e. whether it is feasible for practical,</p><p>commercial and educational research purposes, and how these developments are overcoming the</p><p>barriers for the implementation of DSP algorithms in communication systems for commercial and</p><p>educational use. The tool chain acts as a bridge in between the input resources and output results</p><p>after implementation on hardware. Chapter 1 presents an overview of the thesis. Chapter 2 describes</p><p>iv</p><p>the main tools involved in the rapid prototyping revolution. Chapter 3 describes the role of every</p><p>tool in the flow of rapid prototyping processes. Chapter 4 provides an overview of the previously</p><p>implemented systems using rapid tool chains, their results and our proposed model and</p><p>recommendations. Chapter 5 concludes the results grasped from the previously implemented tool</p><p>chains and theoretical survey made in this thesis.</p>
