FEM(pcode)

说明：  这是一本关于半导体物理学的书籍,从简单的基础入手,希望对相关研究方向的人员有所帮助.(This is a book on semiconductor physics, from the simple basics, hope the staff of the relevant research help.)

说明：  能够精确地提取雷达波的初至时，进行层析成像(Radar can accurately extract the first to when tomography)

mvdr算法，仿真了两个方向的信号方位估计，该算法比常规波束形成要好(mvdr algorithms, simulation of the two directions of signal DOA estimation, the algorithm is better than the conventional beamforming)

语音识别技术的最终目标是要让计算机能与人自由交谈。目前，连续语音识别技术正趋于成熟，语音识别也延伸出了诸多实用化的研究方向。今后，语音识别的重点将集中在自然话语识别与理解、实时语音识别和语音识别鲁棒性等方面。作为一门交叉学科，语音识别所涉及到的技术有信号处理、模式识别、概率论和信息论、发声机理、听觉机理和人工智能等。(The ultimate goal of speech recognition technology is to make computers and allowing others to speak freely. At present, continuous speech recognition technology is maturing, voice recognition is also extended out a lot of practical research directions. In the future, speech recognition will focus on Spontaneous Speech Recognition and Understanding, real-time speech recognition and speech recognition robustness and so on. As an interdisciplinary subject, speech recognition technology involved in a signal processing, pattern recognition, probability theory and information theory, vocal mechanism, hearing mechanism and artificial intelligence.)

< 精通MATLAB综合辅导与指南> 西安交通大学 李人厚 张平安 等译校 这是一本有关MATLAB的参考书，适合于使用MATLAB或正在打算使用MATLAB的读者。本书另辟蹊径可以借助或不借助MATLAB随带的文档资料让读者自学MATLAB。书中口语化的风格,使读者易于阅读。如书名所示,本书提供了读者精通MATLAB所需的工具。作为编程语言和可视化工具,MATLAB具有丰富的一系列功能,可解决工程、科学计算和数学学科中许多问题。本书的基本目的是通过向读者展示如何有效地使用这些功能来帮助读者增强工作能力。由于MATLAB交互式的性质,书中内容以举例方式来描述。在读者阅读本书的同时, 这些例子可以通过运行MATLAB而再现。()

带通滤波 利用自适应AR模型，滤除0.9Hz以下和1.1Hz以上波形(Bandpass filter using adaptive AR model, filter below 0.9Hz and 1.1Hz above waveform)

本压缩包是里面是用matlab编写的QPSK信号调制与解调的程序，程序十分简练。(The compressed package is written in matlab which is QPSK signal modulation and demodulation process, the program is very concise.)

非二进制软译码很实用要学非二进制LDPC的同学可以参考一下(NB-LDPC decode)

说明：  改进的OMP算法，利用残差变化率作为迭代终止条件，提高了运算速度(The improved OMP algorithm uses the residual change rate as the iteration termination condition, which improves the operation speed)
