This book presents millimeter wave communication system design and analysis at the level to produce an understanding of the interaction between a wireless system and its front end so that the overall performance can be predicted. Gigabit wireless commu- nications require a considerable amount of bandwidth, which can be supported by millimeter waves. Millimeter wave technology has come of age, and at the time of writing the standards of IEEE 802.15.3c, WiGig, Wireless HD TM , and the European Computer Manufacturers Association have recently been finalized.

This book is a result of the recent rapid advances in two related technologies: com- munications and computers. Over the past few decades, communication systems have increased in complexity to the point where system design and performance analysis can no longer be conducted without a significant level of computer sup- port. Many of the communication systems of fifty years ago were either power or noise limited. A significant degrading effect in many of these systems was thermal noise, which was modeled using the additive Gaussian noise channel.

Radio propagation measurements and channel modelling continue to be of fundamental importance to radio system design. As new technology enables dynamic spectrum access and higher data rates, radio propagation effects such as shadowing, the presence of multipath and frequency dispersion are the limiting factors in the design of wireless communication systems. While there are several books covering the topic of radio propagation in various frequency bands, there appears to be no books on radio propagation measurements, which this book addresses at length.

n present power system, the engineers face variety of challenges in planning, construction and operation. In some of the problems, the engineers need to use managerial talents. In system design or upgrading the entire system into automatic control instead of slow response of human operator, the engineers need to exercise more technical knowledge and experience. It is principally the engi- neer’s ability to achieve the success in all respect and provide the reliable and uninterrupted service to the customers. This chapter covers some important areas of the traditional power system that helps engineers to overcome the challenges. It emphasizes the characteristics of the various components of a power system such as generation, transmission, distribution, protection and SCADA system. During normal operating conditions and disturbances, the acquired knowledge will pro- vide the engineers the ability to analyse the performance of the complex system and execute future improvement

Recent years have seen a rapid development of neural network control tech- niques and their successful applications. Numerous simulation studies and actual industrial implementations show that artificial neural network is a good candidate for function approximation and control system design in solving the control problems of complex nonlinear systems in the presence of different kinds of uncertainties. Many control approaches/methods, reporting inventions and control applications within the fields of adaptive control, neural control and fuzzy systems, have been published in various books, journals and conference proceedings.

隨著計算機技術和微電子的迅速發展,嵌入式系統已經被廣泛應用到許多領域,如科學研究,工程計算,軍事技術,以及各種商業應用等。聯入式系統被定義為以應用為中心,以計算機技術為基礎,軟硬件可裁剪、適應于特定應用系統對功能、可靠性、成本、體積、功耗、等嚴格要求的專業計算機系統。在目前的各種嵌入式處理器中,由于ARM芯片的功耗低、成本低等顯著優點,因而獲得眾多的半導體廠商的大力支持,在32位嵌入式應用領域獲得了巨人的成功。另一方面,Linx操作系統具有開放源代碼、功能強大,且易于移植等特點而成為嵌入式操作系統的首選,因此在ARM芯片上構建嵌入式Liux系統成為嵌入式領域的一個熱點本文首先總結了ARM體系結構和特點,并選擇了基于AMR920T內核的S3C2440開發板作為移植平臺。然后介紹了搭建交叉編譯環境的一般方法然后介紹了嵌入式 Limux系統的啟動程序實現原理,并實現了ubo的移植,在對 Linux內核結構進行了分析后,給出了 Linux內核的詳細移植的實現方法。然后詳細介紹了如何構建根文件系統,最終把所裁剪的嵌入式系統能夠成功的移植到SC2440開發板上。關鍵詞嵌入式 Linux系統;AM啟動程序;移植:;裁剪嵌入式系統(Embedded System),實際上是"嵌入式計算機系統"的簡稱,它是相對于通用計算機系統而言的。國際電氣與電子工程師協會(IEE)對于嵌入式系統的定義:嵌入式系統是用來控制或監視機器、裝置或工廠等大規模系統的設備。國內對嵌入式系統的一般定義:嵌入式系統是以應用為中心、以計算機技術為基礎、軟件硬件可剪裁、適應于特定應用系統對功能、可靠性、成本、體積、功耗嚴格要求的專用計算機系統嵌入式系統通常由硬件和軟件兩部分組成。硬件由微控制器或單片機實現,包括一些外圍設備,軟件由嵌入式操作系統和應用軟件組成。和通用計算機系統不同,嵌入式系統是與應用緊密結合的,它具有很強的專用性,必須結合實際系需求進行合理的裁剪利用,滿足應用系統的功能,可靠性,成本體積等要求目前,嵌入式技術廣泛應用于智能家電,消費電子,多媒體,網絡工程,衛星通信,軍事工業等領域,具有無限優越的應用前景。
