本程序针对高通公司开发的IS-95通信系统，是一个相对完整的IS-95前向信道的仿真源程序，包括Viterbi编码，数据调制，基于RAKE接收机的解调，实现软判决输入的Viterbi译码等模块，并包括有误码率的计算和性能仿真显示。 (The procedure developed for Qualcomm IS-95 communication system, is a relatively complete IS-95 forward channel simulation source code, including Viterbi coding, data modulation, demodulation based RAKE receiver to achieve soft decision input Viterbi decoding modules, and includes a bit error rate performance computing and simulation show.)

拟合算法的源程序，采用matlab写的，对理解拟合算法有很大的帮助作用。在工程学学习中常用到(Fitting algorithm source code, using matlab write, fitting algorithms for understanding the role of great help. Commonly used in engineering learning)

这一信道模型能够描述由电离层和对流层反射的短波信道，以及建筑物密集的城市环境。12瑞利衰落只适用于从发射机到接收机不存在直射信号（LoS，Line of Sight）的情况，否则应使用莱斯衰落信道作为信道模型(This channel model is able to describe the HF channel reflected by the ionosphere and troposphere, as well as building a dense urban environment. 12 Rayleigh fading only applies to from the transmitter to the receiver there is no direct signal (LoS, Line of Sight), otherwise use Rician fading channel as the channel model)

This document provides a brief description of the models implemented in Matlab/Simulink and used the cases studies presented throughout the book. Although the models were developed in different recent versions of Simulink a final test was conducted in MATLAB R2013a. The models included are the following: • DFIG WT robust model for steady state simulation • DFIG WT robust model for steady state simulation in a HVDC system • Offshore Wind Farm Connection Using Point-to-Point VSC-HVDC (A) (changes in wind farm power output) • Offshore Wind Farm Connection Using Point-to-Point VSC-HVDC (B) (FRT analysis)

本程序模拟日间24个时段光伏出力情况，根据三点估计法求出光伏出力和三点取值的权重(This procedure simulated photovoltaic output is 24 hours in the day, and the photovoltaic output based on three-point estimate method and the weight of three values)

综述了光纤光栅传感器近年来在工程结构健康监测、石油产业、电力行业、岩土工程、航空航天、采矿、爆破、交通及 医学等各个领域的应用情况。文章认为，限制光纤光栅传感器产业化和大规模应用的主要因素是缺乏统一的设计理论 和制作方法，这使得不同厂家生产的传感器规格存在差异。另外，由于复杂的生产技术和精细的生产过程使传感器生产 成本较高，而且能实际应用的光纤光栅传感器的解调产品并不多，且价格很高。根据上述分析，文中对该项技术未来的 发展方向提出了展望。(Overview of FBG sensors in recent years in various fields of engineering structural health monitoring, oil industry, power industry, geotechnical engineering, aerospace, mining, blasting, transportation and medical and other applications. Article that the main factor limiting FBG sensors and large-scale industrial applications is the lack of a unified design theory and production methods, which makes the sensors from different manufacturers specifications differ. In addition, due to the complexity of the production technology and sophisticated production process so that the sensor higher production costs, but also the practical application of fiber grating sensor product is not much, and the price is very high. Based on the above analysis, the article on the future direction of the technology raised the prospect.)
