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

Chapter 2 describes iv the main tools involved in the rapid prototyping revolution. Chapter 3 describes the role of every tool in the flow of rapid prototyping processes. Chapter 4 provides an overview of the previously implemented systems using rapid tool chains, their results and our proposed model and recommendations. Chapter 5 concludes the results grasped from the previously implemented tool chains and theoretical survey made in this thesis.

This thesis is concerned with the use of prototyping during the development of information systems. Prototyping is a process which involves early practical demonstration of relevant parts of the desired system. This is carried out with a view to improving both the quality and timeliness of the target system. The quality of an information system is largely determined by its adequacy as a tool for human users. Prototyping serves to enhance the communication between developers and users, and through this to increase the suitability of the resulting information system. An investigation into the traditional phase oriented approach to systems development reveals that in certain circumstances it can result in incorrect or at best disappointing systems. The prototyping approach is examined as a possible alternative. Particular attention is paid to its use with respect to typical characteristics of information systems. This is followed by an investigation into all aspects of prototyping. One aspect, that of the construction of prototypes, is dealt with separately and includes an examination of a variety of tools and techniques. Three of these approaches form part of an experiment in building prototypes. Each method is used to build prototypes of the same system. This provides the opportunity to compare approaches in terms of time, cost, and ease of maintenance, with the existing system. Prototyping is used during the development of a genuine system in a commercial environment. Special consideration is given to both the organisation and the control of prototyping. This project is closely monitored and documented in detail. In conclusion, recommendations are made concerning the use of prototyping during information systems development. Further research areas are also highlighted.

This project investigates shaping the design practice of a trans-disciplinary creative agency through engagement with research and prototyping. The intention has been to identify and test prototyping processes that permit the generation of novel technological and design solutions that are then recognised as valuable to the project clients. The project research explores a central question in the prototyping of new design solutions. That of who is given access to the prototyping processes and how this affects the efficacy and relevance of the processes and the acceptance of the results. The project research describes three successive modes of engaging complex client bodies in innovative designs encompassing customer service in new spatial configurations. The first mode takes client representations at face value, the second engages the wider client in workshops, and the third involves the wider client in the inclusive design of full-scale prototypes. The findings su ggest that the tangible outcomes of a prototyping process can act as uniquely valuable bridges for introducing and testing new design solutions for clients. These processes help reduce the perceived risk of innovation and promote conversation and dialogue among the diverse and often non-aligned project participants. The project describes ways in which this setting up of the prototyping processes can also contribute significantly to the nature and value of the design outcomes. The prototyping process can begin to act as an idea generator and catalyst. The processes can focus all those involved in contemplating the value of innovation rather than the expressing of concern over the risks involved in addressing change.

The Ozlab user-test facility at Karlstad University needs to be reprogrammed. This paper will be used as a decision support document for the redesigning. Ozlab is currently depending on a discontinued software, the learning curve is too steep for new users and there are a number of flaws in the system that force the user to take detours to complete some simple tasks. Ozlab uses the Wizard-of-Oz technique. The Wizard-of-Oz technique is a method used for conducting user tests on prototypes with no functionality; instead a “wizard” controlling the test person’s computer from the next room provides the interaction. There are no general Wizard-supporting tools in the world except for Ozlab. When developing the solution for Ozlab it is important to keep this unique concept, but make the Ozlab system fit for the future and long term sustainable.   For this paper, interviews with different kinds of users were conducted to map what is most important for them in a future Ozlab. Moreover, reliance on other programs and file formats than the present ones is also discussed. These other programs and file formats are evaluated on how well they support the optimal workflow for creating and testing a prototype in Ozlab. Recommendations are made with the conclusion that an XML-based solution is the most appropriate option, because the biggest concerns are to make Ozlab as independent from software and file formats as possible, and to make sure that maintenance is easy. Other solutions discussed are based on the Adobe Photoshop software and the HTML5 format.
