Abstract

Data modem design has attracted a lot of scientific and commercial interest for more than three decades now. The field is important from a scientific point of view, since reliable data communications require very sophisticated solutions to many associated problems. From a commercial point of view its importance arises from the ever- rising needs for Computer networking and distributed processing in general. Modem algorithms are real-time in nature, so adequate technological support is important for modem design development. Advances in VLSI are opening new possibilities in this area and current trends toward integration of computing and communications are placing new demands on its further development. One can say that data modem design is entering its renaissance and this fact was our motivation in preparing this text. The objective is to bridge the gap between the increasing number of published papers on modem design and implementation, and the rapidly growing interest in the field. Included in the text are topics to introduce and familiarize the reader with modem design. Topics covered include: microprocessor applications in communications, data modem types, microprocessor and VLSI types, and technological impacts on design. Finally, we address the hardware issues such as the processor elements and interfacing, and software issues like the digital filter implementation. A comprehensive bibliography on modem design and implementation is also provided. With this bibliography one can research VLSI/microprocessor-based data modem design easily and thoroughly.
