New Media Futures
Daniel Faltesek; Daniel Adams · Oregon State University · 2019
This book is intended for use in a large introductory class in new media in a program that covers the “full-stack” including critical/cultural studies, media management, diffusion of innovation, and synthetic media production. The first half of this basic sequence covered new media and democracy, finance, intellectual property law, basic games, and transmedia. The second half of the sequence covers many topics related to aesthetics, design, technology, and methodology. To that end, this book needed to be written so that it would be helpful for many different professors and trajectories of study. This book is in neither engineering, social science, nor the humanities, but also all of those. At the same time, this is a program in the Communication Studies and Media Studies traditions of the United States and that texture will come across.

Introduction to Communication Systems: An Interactive Approach Using the Wolfram Language
Victor Frost · University of Kansas Libraries · 2021
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.
