Designing Discrete and Digital Communication Systems
In this chapter, the practical aspects of the design of digital discrete communication systems, primarily digital signal processors and field -programmable gate arrays, are analysed. The systems are presented at the level of block schematics, to address the main issues in their design and discuss the advantages and disadvantages of various designs in digital technology. Designs using quadriphase-shift keying and quadrature amplitude modulation are presented separately. The operation of each system is explained in terms of the theoretical structure of the system, which allows a clear understanding of the relationship between the theoretical model of the system and its practical design. The structures of the first, second, and third generation of discrete transceiver designs are presented and discussed.
