商品描述
Understanding radio communications systems unlocks a new way to look at the world and the radio waves that connect it. Through easy-to-understand instruction and a variety of hands-on projects, this book gives the reader an intuitive understanding of how radio waves propagate, how information is encoded in radio waves, and how radio communications networks are constructed.
This book also focuses on the world of amateur, or "ham," radio, a global network of hobbyists that experiment and communicate with radio waves. The reader can learn what amateur radio is, how one can obtain an amateur radio license, and how various pieces of amateur radio hardware work.
Rather than overwhelm with formulas and numerical approaches, this book presents an easy-to-follow qualitative approach to the theory aspects of radio--perfect for those with little to no knowledge of electromagnetism, signal processing, or hardware development. Instead, instruction focuses on hands-on learning. Radio waves are easy and inexpensive to manipulate with modern hardware, so the examples throughout this text provide ample opportunity to develop an understanding of such hardware.
A special focus is given to applications of radio communications in the modern world. In every chapter, the reader gains new insight into different radio communications systems and the hardware and software that makes it all possible. Projects include using a software-defined radio to download live images of the Earth from weather satellites, Arduino-based digital radio communications networks, making amateur radio contacts, and more.
What You'll Learn:
-
- Encode information in radio waves
- Obtain an amateur radio license
- Use important pieces of radio communications hardware, such as antennas, handheld transceivers, software-defined radios, radio repeaters, and more
Who This Book Is For
Anyone interested in modern communications, from high school and college students pursuining STEM to professionals looking to broaden their understandings of radio

理解無線通信系統為我們提供了一種全新的視角來看待世界及其連接的無線電波。這本書通過易於理解的教學和各種實作專案,讓讀者直觀地理解無線電波是如何傳播的、信息是如何編碼在無線電波中的,以及無線通信網絡是如何構建的。
這本書還專注於業餘無線電(或稱「哈姆」無線電)的世界,這是一個由愛好者組成的全球網絡,他們利用無線電波進行實驗和通信。讀者可以了解什麼是業餘無線電、如何獲得業餘無線電執照,以及各種業餘無線電硬體的運作方式。
這本書並不會用公式和數值方法讓人感到不知所措,而是以易於跟隨的定性方法來介紹無線電的理論方面,這對於對電磁學、信號處理或硬體開發幾乎沒有了解的人來說非常合適。相反,教學重點放在實作學習上。現代硬體使得操作無線電波變得簡單且便宜,因此本書中的範例提供了充分的機會來發展對這些硬體的理解。
本書特別關注無線通信在現代世界中的應用。在每一章中,讀者都能獲得對不同無線通信系統及其背後的硬體和軟體的新見解。專案包括使用軟體定義無線電從氣象衛星下載地球的實時影像、基於Arduino的數位無線通信網絡、進行業餘無線電聯絡等。
你將學到的內容:
- 在無線電波中編碼信息
- 獲得業餘無線電執照
- 使用重要的無線通信硬體,如天線、手持收發器、軟體定義無線電、無線電中繼器等
本書適合誰閱讀
任何對現代通信感興趣的人,從追求STEM的高中和大學生到希望擴展無線電理解的專業人士。
