压缩算法，matlab。很棒好的代码，要下的赶快了啊(Compression algorithm, MATLAB. Great good code to the next, quickly)

说明：  写一个程序，用户依照流行歌曲的人气调查表，将相关数据输入到计算机文件中，计算机按照人气指数将排名前十位的歌曲信息显示并存储到文件中。(Write a program, the user in accordance with the popularity of pop music questionnaire, data will be entered into the computer files, the computer will be ranked according to popularity index of the top ten song information display and store the file.)

说明：  时频分析（GUI），非常适合观察研究非平稳信号的时频特性(Time-Frequency Analysis)

最小费用流问题用于求解，图论中两地区运输费用最少的问题，本程序通过MATLAB解决这一问题(For solving the minimum cost flow problem in graph theory two least-cost regional transportation issues, the procedure to solve this problem through MATLAB)

利用matlab软件设计并仿真下面的无线通信系统。模拟信源为单音频信号。模拟调制方式为ASK。信道为多径信道（仿真中2径），信道中噪声为加性高斯白噪声。采用相干解调接收。画出了解调器输出端性能曲线与点信噪比SNR的关系。(Software design and simulation using matlab the following wireless communication systems. A single analog audio signal source. Analog modulation is ASK. Channel multi-path channel (simulation 2 diameter), channel noise is additive white Gaussian noise. The use of coherent demodulation receiver. Draw the output of the demodulation performance curve and the point of the relationship between signal to noise ratio SNR.)

RSSI算法是指根据无线传感器接受到（目标物体）的信号指示强度，计算该信号在传播中的损耗，根据理论或者经验的信号传播模型将信号强度转换成距离。但是这种算法很容易受到天气，障碍物或人员流动的影响，导致测距不精确，从而定位精度不高。但是由于RSSI算法简单，成本低廉，很多无线通信模块提供RSSI值，所以RSSI算法依然应用在众多领域中。(RSSI algorithm is based on wireless sensor to receive the signal intensity (objects), calculate the signal in the transmission loss, according to the experience of the theory or the signal propagation model will be converted into a distance of signal strength.But this algorithm is very vulnerable to weather, obstacles or the influence of the flow of people, lead to range is not accurate, thus positioning accuracy is not high.But because the RSSI algorithm is simple, low cost, a lot of wireless communication module provides RSSI values, so the RSSI algorithm is used in many fields.)

具有检测FIR滤波器单位脉冲响应h[n]中零系数（zero tap detection）功能的LMS算法自适应均衡器，可处理相关输入（colored inputs)和独立输入(white inputs). 检测出零系数的个数和位置,减少后续计算次数，提高算法效率。(Zero Tap Detection LMS adaptive Equalizer with Tap Decoupling techniques and Colored Inputs and white inputs.)
