tailieunhanh - Practical Digital Wireless Signals

Wireless communications is rapidly becoming one of the ubiquitous technological underpinnings of modern society (such as electric power, fossil fuels, automobiles, etc.). Few people think about the technology within their mobile phones, remote controls, garage door openers, GPS navigation devices, and so on. They are always at hand and reliably work for the user. Yet even within the electrical engineering (EE) community, radio communication techniques have a reputation as a “Black Art” that can only be successfully practiced by “RF people”. This is changing, albeit slowly. Any significant progress in successfully opening this vital technology widely to more practitioners must remove this “Black Art” stigma. In my opinion this. | Practical Digital Wireless Signals Do you need to know what signal type to select for a wireless application Quickly develop a useful expertise in digital modulation with this practical guide based on the author s experience of over 30 years in industrial design. You will understand the physical meaning behind the mathematics of wireless signals and learn the intricacies and tradeoffs in signal selection and design. Key features Six modulation families and 12 modulation types are covered in depth A quantitative ranking of relative cost incurred to implement any of 12 different modulation types Extensive discussions of the Shannon Limit Nyquist filtering efficiency measures and signal-to-noise measures Radio wave propagation and antennas multiple access techniques and signal coding principles are all covered Spread spectrum and wireless system operation requirements are presented. Earl McCune is a practicing engineer and Silicon Valley entrepreneur. A graduate of UC Berkeley Stanford University and UC Davis he has over 30 years of post-graduate industry experience in wireless communications circuits and systems. Now semi-retired he has founded two successful start-up companies each of them winning industrial awards for their technical innovation. the CAMBRIDGE RF and microwave engineering series Series Editor Steve C.
