Chapter 5 covers the aspects of using various linear equalizers in a simple communication link. Chapter 4 covers the performance simulation using the models built in Chapter 3. Chapter 3 covers the complex baseband equivalent models for techniques such as M-ary PAM, M-ary PSK, M-ary QAM and M-ary FSK modulations. Power spectral density (PSD) and performance analysis for these techniques are also provided. Chapter 2 covers the waveform simulation technique for the following digital modulations: BPSK, differentially encoded BPSK, differential BPSK, QPSK, offset QPSK, pi/4 QPSK, CPM and MSK, GMSK, FSK. Concepts covered in this chapter include- signal generation techniques for generating well known test signals, interpreting FFT results and extracting magnitude/phase information using FFT, computation of power and energy of a signal, various methods to compute convolution of two signals. Chapter 1 introduces some of the basic signal processing concepts that will be used throughout this book. Additionally, simulation and performance of receiver impairments are also provided in a separate chapter. Performance simulations of well known digital modulation techniques are also provided. Waveform simulation technique and the complex equivalent baseband simulation model will be provided on a case-by-case basis. As for the topics concerned, only the basic techniques of modulation and demodulation of various digital modulation techniques are covered. The Matlab scripts carry inline comments intended to help the reader understand the flow of implementation. For each topic discussed, a short theoretical background is provided along with the implementation details in the form of Matlab scripts. Theoretical aspects of digital modulation techniques will be kept brief. Readers may consult other textbooks and documentations that cover those topics. I assume that the reader has a fair understanding on the fundamentals of programming in Matlab. I intend the book to be used primarily by undergraduate and graduate students in electrical engineering discipline, who wish to learn the basic implementation aspects of a modulation demodulation technique. This provides an opportunity for a practicing engineer to understand the basic implementation aspects of modeling various building blocks of a digital modulation system. Most of the simulation models shown in this book, will not use any of the inbuilt communication toolbox functions. In this book, I intend to show how the theoretical aspects of a digital modulation-demodulation system can be translated into simulation models, using elementary matrix operations in Matlab. These built-in functions or toolboxes hide a lot of background computations from the user thereby making it difficult, especially for a learner, to understand how certain techniques are actually implemented inside those functions.

Predominantly, such books utilize the sophisticated built-in functions or toolboxes that are already available in software like Matlab. Only a handful of books provide insight on how these techniques can be modeled and simulated. Most of them underscore different theoretical aspects of design and performance analysis of digital modulation techniques.

ISBN:ģ Preface There exist many textbooks that provide an in-depth treatment of various topics in digital modulation techniques.
