实现数字接收机的基本功能,包括信道均衡，载波恢复，同步恢复，匹配滤波器等(The basic functions of digital receivers，Including channel equalization, carrier recovery and synchronization recovery, the matched filter )

This is a procedure for computing small-world .For large complex networks, understandably, their sheer size is very important. This procedure is useful.

Example of application in kalman filter

《通信系统仿真原理与无线应用》系统地介绍通信系统的设计、分析和仿真方法，还提供了大量极具参考价值的仿真实例。《通信系统仿真原理与无线应用》的全部仿真程序都是采用MATLAB编写的。这不仅方便读者理解仿真的实现过程，还允许读者修改或使用这些代码段来进行自己的仿真开发。章后提供了大量的参考文献和经过精心设计的各类练习题，方便教学。此为中文翻译本。(Principles of Communication Systems Simulation with Wireless Applications is a hands-on, example-rich guide to simulating wireless communications systems. The first book to present complete MATLAB simulation models for predicting the impact of design changes, it treats every aspect of simulation: sampling, signal and system representations, filters, noise, Monte Carlo simulation, postprocessing, nonlinear and time-varying systems, waveform and discrete channels, co-channel interference, and more. It includes four detailed case studies.)

说明：  有监督的特征选择和优化程序MATLAB代码，基于最小二乘算法。内有测试数据，和详细程序说明(Least-Squares Feature Selection (LSFS) is a feature selection method for supervised regression and classification. LSFS orders input features according to their dependence on output values. Dependency between inputs and outputs is evaluated based on an estimator of squared-loss mutual information called LSMI)

有关matlab的数值计算求导方法，对以后数值计算的求导很实用。(About matlab numerical calculation method of derivation, for subsequent numerical derivation is very practical.)

说明：  VAD matlab程序 常见于无声帧检测 语音信号处理(VAD matlab program is commonly used in silent frame detection speech signal processing)
