Advanced techniques for digital receivers
Phillip E. Pace
Beginning with a review of signal theory, circuit design, and filters, it describes the circuit design of high-performance analog-digital converters incorporating exotic semiconductor and electro-optical components such as Mach-Zehnder interferometers, fiber lattice accumulators, and mode-locked lasers, as well as superconducting Josephson Junctions and SQUIDs. Also contains a brief chapter on digital radio frequency memory (DRFM). The main focus of the book is folding ADCs. Sigma-delta and folding ADCs are thoroughly explained and used to explain symmetrical number system (SNS) and optimum SNS ADCs. Finally, some applications of electronic and electro-optical OSNS in undersampling digital receivers and phase-sampling DF antennas are described.
The book contains numerous equations, simulation results, block diagrams, and logic designs, and includes a floppy with MATLAB and SIMULINK programs. A set of exercises is given after each chapter. The reader is also expected to use SPICE in some of the exercises. The reader should be familiar with digital signal processing, Fourier transforms, and circuits. Design problems and tradeoffs among different architectures are clearly discussed. There is less emphasis on electro-optical architectures and more on ADCs than would be expected from the book's description.
