This ebook provides a unique pedagogical approach to teaching the fundamentals of communication systems using interactive graphics and in-line questions. The material opens with describing the transformation of bits into digital baseband waveforms. Double-sideband suppressed carrier modulation and quadrature modulation then provide the foundation for the discussions of Binary Phase Shift Keying (BPSK), Quadrature Phase Shift Keying (QPSK), M-ary Quadrature Amplitude Modulation (M-QAM), M-ary Phase Shift Keying (MPSK), and the basic theory of Orthogonal Frequency Division Multiplexing (OFDM). Traditional analog modulation systems are also described. Systems trade-offs, including link budgets, are emphasized. Interactive graphics allow the students to engage with and visualize communication systems concepts. Interactivity and in-line review questions enables students to rapidly examine system tradeoffs and design alternatives. The topics covered build upon each other culminating with an introduction to the implementation of OFDM transmitters and receivers, the ubiquitous technology used in WiFi, 4G and 5G communication systems.
This ebook is provided in the Computable Document Format (CDF) and reading the CDF file requires the Wolfram Player 12.3 (see wolfram.com/player).
This is an open source, open content and open access ebook introducing the concepts of digital and analog communication systems. The purpose of this presentation of the fundamentals of communication systems is to bring the material alive through the use of interactive graphics, dynamic performance metric calculations, and in-line interactive questions. The ebook contains 348 figures of which 104 are interactive graphics. The instructor version of the ebook is compatible with a licensed version of Mathematica desktop version 12.3. Instructors can lecture directly from the ebook using Mathematica's "Classic Slide Show" functionality. Separate Mathematica notebooks containing solutions for the end-of-chapter questions are available enabling instructors the ability to change the problems and obtain new solutions. The instructor and homework notebooks are available to upon request (contact vsfrost@ku.edu).
