这是搜集的TIME评选出了08年50个最棒的网站-This is a collection of TIME selected the 50 best in 2008 website

说明：  电机的测试平台，可测电流，热电偶，转速，与yokokawa的测功机通讯，并记录为xls数据表的程序(Motor test platform, measurable current, thermocouples, speed, and the dynamometer yokokawa communications, and record the data tables for the procedure xls)

说明：  程序实现的主要功能： OFDM调制识别：研究了基于高阶累量和基于小波变换的OFDM信号和单载波调制信号的识别算法，仿真分析了两种算法在高斯信道和多径瑞利衰落信道下的信号识别性能。 OFDM参数估计：研究了基于Welch算法和AR模型法求解功率谱进而估计信号带宽的算法，对两种算法的估计性能进行了比较；根据OFDM信号的循环平稳性研究了基于循环谱的载频估计算法；根据 OFDM信号的自相关性研究了基于可变延时自相关和固定延时自相关的FFT相结合的算法，估计了OFDM信号的有效数据长度、符号总长度、循环前缀长度和子载波间隔；最后研究了基于带宽和基于过采样估计子载波数目两种算法，并在高斯信道和多径瑞利衰落信道下对以上参数估计算法进行了仿真分析。 其中OFDM_DEMO为整个项目的程序入口，其余均为辅助函数，每一个函数均有参数注释和功能说明。(The main functions of the program are as follows: OFDM modulation recognition: the recognition algorithms of OFDM signal and single carrier modulation signal based on high-order cumulant and wavelet transform are studied. The signal recognition performance of the two algorithms in Gaussian channel and multi-path Rayleigh fading channel is simulated and analyzed.)

说明：  目前我们的生活中到处都有基于ARM架构的芯片，移动互联网时代到来之后，尤其在智能手机领域，ARM可以说是处于统治地位，其他的类似平板电脑以及安卓设备等也都在采用ARM架构。 不过虽然ARM应用这么广泛，但是相关教材却比较少，让很多爱好者学习比较困难，而《ARM汇编语言官方手册》这本官方手册的发布给正在研究ARM汇编的人们提供了很大的帮助。文末有《ARM汇编语言官方手册》pdf免费资源分享，欢迎大家下载学习。 《ARM汇编语言官方手册》一共分为7个章节，不仅详细介绍了ARM的体系结构，还对汇编语言模块进行了深入的探究。手册中整理了绝大部分汇编中可能遇到的语法格式问题和ARM指令，给从业者研究ARM带来了很大的便利。 如果你想要赶上万物智联和人工智能的风潮并加入其中，那ARM绝对不可错过，现在文末免费分享《ARM汇编语言官方手册》PDF版本，欢迎下载学习。(At present, there are chips based on ARM architecture everywhere in our life. After the arrival of the mobile Internet era, especially in the field of smart phones, arm can be said to be in the dominant position. Other similar tablet computers and Android devices are also using ARM architecture. However, although arm is widely used, there are few related teaching materials, which makes it difficult for many lovers to learn. The official Manual of arm assembly language provides great help for people who are studying arm assembly language. At the end of the article, there is "arm assembly language official manual" PDF free resource sharing, welcome to download and learn.)
