{"product_id":"digital-communications-isbn-9781119091257","title":"Digital Communications","description":"\u003cp\u003eThis is a modern textbook on digital communications and is designed for senior undergraduate and graduate students, whilst also providing a valuable reference for those working in the telecommunications industry.  It provides a simple and thorough access to a wide range of topics through use of figures, tables, examples and problem sets.  The author provides an integrated approach between RF engineering and statistical theory of communications.  Intuitive explanations of the theoretical and practical aspects of telecommunications help the reader to acquire a deeper understanding of the topics.  The book covers the fundamentals of antennas, channel modelling, receiver system noise, A\/D conversion of signals, PCM, baseband transmission, optimum receiver, modulation techniques, error control coding, OFDM, fading channels, diversity and combining techniques, MIMO systems and cooperative communications.  It will be an essential reference for all students and practitioners in the electrical engineering field.\u003c\/p\u003e \u003cp\u003ePreface xiv\u003c\/p\u003e \u003cp\u003eList of Abbreviations

Professor Safak achieved his PhD on the topic of Antennas, and he taught electromagnetic theory and antennas before joining NATO in the Hague, Netherlands, where he worked on military satellite communications. Following this wide and multi-disciplined exposure, Safak returned to academia and taught courses in digital communications. He is currently a member of the CONASENSE Foundation which studies visionary projects in Communications, Navigation, Sensors and Services. Teaching and supervising remain his priority, however, and this book is the result of many years' lecture work, plus the most recent research outcomes.","brand":"Wiley","offers":[{"title":"Default Title","offer_id":47989064532197,"sku":"NP9781119091257","price":93.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1842\/7735\/files\/9781119091257.jpg?v=1761782646","url":"https:\/\/k12savings.com\/es\/products\/digital-communications-isbn-9781119091257","provider":"K12savings","version":"1.0","type":"link"}
