The goal of this book is to provide a concise but lucid explanation and deriva-
tion of the fundamentals of spread-spectrum communication systems. Although
spread-spectrum communication is a staple topic in textbooks on digital com-
munication, its treatment is usually cursory, and the subject warrants a more
intensive exposition. Originally adopted in military networks as a means of
ensuring secure communication when confronted with the threats of jamming
and interception, spread-spectrum systems are now the core of commercial ap-
plications such as mobile cellular and satellite communication.

The first practical examples of mobile communications were used in many countries like
the USA, the UK and Germany in military services, and played a significant role in the
First World War to transfer important information from the front to headquarters to take
further actions. Good and secure wireless communications were an important need for all
military services – army, navy and air force. In this respect, the Second World War was a big
experimental battlefield for the development and evolution of mobile radio. It was in the
interests of governments that after the Second World War the military investment should
be paid back by civilian use, and all western European countries started their so-called first
generation of mobile communication networks.

The term “ smart grid ” defi nes a self - healing network equipped with dynamic optimiza-
tion techniques that use real - time measurements to minimize network losses, maintain
voltage levels, increase reliability, and improve asset management. The operational data
collected by the smart grid and its sub - systems will allow system operators to rapidly
identify the best strategy to secure against attacks, vulnerability, and so on, caused by
various contingencies. However, the smart grid fi rst depends upon identifying and
researching key performance measures, designing and testing appropriate tools, and
developing the proper education curriculum to equip current and future personnel with
the knowledge and skills for deployment of this highly advanced system.

The electrical power grid is often referred to as one of the most complex man-
made systems on Earth. Its importance to all aspects of our daily lives, economic
stability, and national security cannot be overstated, and the need for an updated,
secure, resilient, and smarter power grid infrastructure is increasingly recognized
and supported by policy makers and market forces.

Sensors are points ofcontact betweenthe material world ofatoms, mass, andenergy
and the seemingly immaterial world of information, computation, and cognition.
Linking these two domains more tightly yields all sorts of practical benefits, such as
improvedinputdevicesforcomputers,moreeffectivemedicaldevices(implantedor
worn), more precise agricultural operations, better monitored buildings or bridges,
more secure payment systems, and more reliable sensor–actuator control systems.
There are many settings in which tighter coupling between digital and physical
planes can enhance safety, security, performance, and reliability.

If the space around us could adapt to our needs and intentions, then our lives
would be much simpler. We would have to spend less time on our daily chores,
we would be more productive and, hopefully, we would live in a less worrisome
and, most likely, more secure world

1:打開J-Flash ARM后,首先點(diǎn)擊File-OpenProject...,從中選擇STM32F103RB.jflash。(例子芯片,直接在提示的目錄下找) 2.點(diǎn)擊File-Open data file...選擇要燒錄的可執(zhí)行文件(.hex 或者 .bin) 3:options-project settings 在里面配置cpu型號(hào),下載方式 4: 選擇燒錄文件后,點(diǎn)擊Target-connect,鏈接一下硬件是否通。如果能夠連接成功會(huì)了LOG窗口最后一行顯示“Connected successfully”。5:按F3擦除芯片。6.按F5鍵將程序?qū)懭胄酒?.硬件鏈接上之后，點(diǎn)擊Target-secure chip防止程序被惡意讀出。如果您的芯片用于調(diào)試，不要執(zhí)行本步驟。
