This work titled A DIGITAL Phase Locked Loop based Signal and Symbol Recovery System for Wireless Channel is intended to serve as a document covering funda- mental concepts and application details related to the design of DIGITAL phase locked loop (DPLL) and its importance in wireless communication. It documents some of the work done during the last few years covering rudimentary design issues, complex implementations, and fixing configuration for a range of wireless propa- gation conditions.

Optical communication technology has been extensively developed over the last 50 years, since the proposed idea by Kao and Hockham [1]. However, only during the last 15 years have the concepts of communication foundation, that is, the modulation and demodulation techniques, been applied. This is pos- sible due to processing signals using real and imaginary components in the baseband in the DIGITAL domain. The baseband signals can be recovered from the optical passband region using polarization and phase diversity tech- niques, as well as technology that was developed in the mid-1980s.

While teaching classes on DIGITAL transmission and mobile communications for undergraduate and graduate students, I was wondering if it would be possible to write a book capable of giving them some insight about the practical meaning of the concepts, beyond the mathematics; the same insight that experience and repetitive contact with the subject are capable to construct; the insight that is capable of build- ing the bridge between the theory and how the theory manifests itself in practice.

The design and manufacturing of wireless radio frequency (RF) transceivers has developed rapidly in recent ten yeas due to rapid development of RF integrated circuits and the evolution of high-speed DIGITAL signal processors (DSP). Such high speed signal processors, in conjunction with the development of high resolution analog to DIGITAL converters and DIGITAL to analog converters, has made it possible for RF designers to digitize higher intermediate frequencies, thus reducing the RF section and enhancing the overall performance of the RF section.

The field of DIGITAL communication has evolved rapidly in the past few decades, with commercial applications proliferating in wireline communi- cation networks (e.g., DIGITAL subscriber loop, cable, fiber optics), wireless communication (e.g., cell phones and wireless local area networks), and stor- age media (e.g., compact discs, hard drives). The typical undergraduate and graduate student is drawn to the field because of these applications, but is often intimidated by the mathematical background necessary to understand communication theory.

In this paper we revisit hybrid analog-DIGITAL precoding systems with emphasis on their modelling and radio-frequency (RF) losses, to realistically evaluate their benefits in 5G system implementations. For this, we decompose the analog beamforming networks (ABFN) as a bank of commonly used RF components and formulate realistic model constraints based on their S-parameters. Specifically, we concentrate on fully-connected ABFN (FC-ABFN) and Butler networks for implementing the discrete Fourier transform (DFT) in the RF domain. The results presented in this paper reveal that the performance and energy efficiency of hybrid precoding systems are severely affected, once practical factors are considered in the overall design. In this context, we also show that Butler RF networks are capable of providing better performances than FC-ABFN for systems with a large number of RF chains.

Multi-carrier modulation‚ Orthogonal Frequency Division Multi- plexing (OFDM) particularly‚ has been successfully applied to a wide variety of DIGITAL communications applications over the past several years. Although OFDM has been chosen as the physical layer standard for a diversity of important systems‚ the theory‚ algorithms‚ and implementation techniques remain subjects of current interest. This is clear from the high volume of papers appearing in technical journals and conferences.

This book stems from its ancestor DIGITAL Transmission Theory,published by Prentice-Hall in 1987 and now out of print. Following the suggestion of several colleagues who complained about the unavailability of a textbook they liked and adopted in their courses, laying a strong emphasis on wireless communication. We hope that those who liked the previous book will find again its flavor here,while new reader, untouched by nostalgia, will judge it favorably.
