一个IEEE802.11b的实用例程，供大家参考。以5.5Mbps 为例。(5.5 Mbps CCK Simulation using specs from IEEE 802.11b, No guarantees and warantees!)

％ 用途：选列主元Gauss消去法解线性方程组ax=b ％ 格式：x=nagauss2(a,b,flag) a为系数矩阵，b为右端列向量，flag若为0，则显示中间过程 ％ 否则不显示，默认值为0，x为解向量 ( Usage: Selected Principal Gauss elimination method solution of linear equations ax = b format: x = nagauss2 (a, b, flag) a for the coefficient matrix, b for the right side column vector, flag if it is 0, it shows the middle Otherwise, the process does not appear, the default value is 0, x for the solution vectors)

motion tracking to detect and track moving objects through a sequence of images

单点采用能量检测法，局限性大，于是采用多点分布式合作检测(Single point of using energy detection method, the limitations of large, so the detection of multi-point distributed cooperation)

求传递函数的一般格式，通过该程序，我们基本上能写出求任意的传递函数的式子(The general format of the transfer function of demand。Through this program, we can write the formula basically seeking arbitrary transfer function)

This paper helps in Blind Identification and Equalization of MIMO FIR Channels Based on Subspace Decomposition and Independent Component Analysis

onvif开发相关 实现了onvif基本功能(onvif development，have it s basic function.)

关于端点检测的几种方法，语音样本是自己录制的，对传统算法做了一些改进，加入了去噪，去噪之后再进行端点检测，均调通 vad0303：自己设置调整门限为一定值 vad0310：根据能量值和过零率设置门限，自适应门限值 vad0310_2：基于比例因子的门限自调整 vad0310.m加入了噪声，端点检测前都噪声进行了处理 entropy.m：基于自适应子带频谱熵的稳健性语音端点检测 可用于语音增强及端点检测 dbdoor.m：双门限算法，用于语音端点检测。可以通过调整门限值，并加入门限自适应算法，实现语音端点检测(Several methods on endpoint detection, recording their own voice samples, the traditional algorithm has made some improvements, adding a de-noising, and then after de-noising endpoint detection are transferred through)

用matlab的imagesc函数模拟液体表面分子蒸发的过程，并且程序整体按字母分为a到q一共17个部分，依次解释了程序的生成过程(matlab imagesc)

曲线标注程序是MATLAB的一个源程序！CURVE NOTING (curve tagging procedure is a source of MATLAB! CURVE NOTING)
