　介绍了暖通空调系统(HVAC) 故障检测与诊断(FDD) 的概念,发生故障的原因以及主要的故障检测与诊断方 法,比较了常用的故障检测与诊断方法的优缺点,分析了国内、外暖通空调故障检测与诊断的研究现状和应用情况,对暖 通空调故障检测与诊断的发展过程与方向进行了总结和展望(Introduction of the HVAC system (HVAC) fault detection and diagnosis (FDD) concept, the reasons for failure as well as major fault detection and diagnosis methods, compared the commonly used method of fault detection and diagnosis of the strengths and weaknesses, analyzes the domestic and foreign HVAC Fault Detection and Diagnosis Research and application of HVAC Fault Detection and Diagnosis with the direction of the development process are summarized and prospects)

Cellular Authentication for Mobile and Internet Services introduces the reader into the field of secure communication for mobile applications, including secure web browsing with a phone or PC, Single Sign-On (SSO), mobile broadcast content protection, secure location services, etc. The book discusses the Generic Authentication Architecture (GAA) of the mobile standardization body 3rd Generation Partnership Project (3GPP) and its American counterpart 3GPP2 in full detail and with all variants. It explains the usage of GAA by various standardization bodies and standardized applications, and also looks at a number of non-standardized ones, such as secure remote login to enterprise environment and card personalization.

经典matlab算法，好好学习的话，收益很大的 呵呵(perfect matlab materials)

说明：  常规OFDM系统容易导致ICI，为了消除ICI，在信号传输前进行编码，本系统为1/2PCC编码，提高系统效率。(Conventional OFDM system easily lead to ICI, is encoded in the signal before transmission, in order to eliminate ICI, this system for 1/2PCC encoding to improve system efficiency.)
