应用背景Matlab is an ideal tool for simulating digital communications systems, thanks to its easy scripting language and excellent data visualization capabilities. One of the most frequent simulation tasks in the field of digital communications is bit-error- rate testing of modems. The bit-error-rate performance of a receiver is a figure of merit that allows different designs to be compared in a fair manner. Performing bit-error-rate testing withMatlab is very simple, but does require some prerequisite knowledge.关键技术主要说明了如何利用matlab对比特错误率进行仿真。从以下几个方面给予说明：采样信号的特点、发送信号模型、建立SNR、确定Eb、确定N0、计算噪声方差、加性噪声等，步骤非常详细，为差错控制编码进行BER仿真提供强有力的解释。

里面有用MATLAB自编的几个数值计算方面的几个程序，有拉格朗日多项式插值法，高斯消去法求解方程组，最小二乘法拟合，复合梯形公式求解数值积分(Some Useful MATLAB self inside the numerical calculation of the number of procedures, Lagrange polynomial interpolation method, Gaussian elimination method for solving equations, least squares fitting, composite trapezoidal formula for numerical integration)

matlab中的标准svm程序源码，用于解决线性的回归问题，不能用于解决非线性，区别于最小二乘支持向量机。(svm program source code, standard Matlab is used to solve linear regression problems, can not be used to solve nonlinear, different from the least squares support vector machine.)

Corner is important feature points in the image corners with processing information, the amount of data is relatively small, but the large amount of information. Corner has not clearly defined, research and analysis of diagonal point algorithm and comparison is necessary

应用背景  现代工业通用机械都配备了相当数量的滚动轴承。一般说来，滚动轴承都是机器中最精密的部件。通常情况下，它们的公差都保持在机器的其余部件的公差的十分之一。但是，多年的实践经验表明，只有10%以下的轴承能够运行到设计寿命年限。而大约40%的轴承失效是由于润滑引起的故障，30%失效是由于不对中或“卡住”等装配失误，还有20%的失效是由过载使用或制造上缺陷等其它原因所致。 关键技术对于非平稳信号的谱峭度是关于频率和频率分辨率的函数，因此基于FIR带通滤波器的快速谱峭度算法将其成功的应用于实际的故障诊断之中。此算法是基于二叉树状滤波器组结构的。
