matlab编制的通过卷积完成特征点匹配的软件(match image feature points by correlation)

改程序包里包含中值、均值滤波、自适应中值滤波和一种改进的椒盐噪声滤波程序，前三种是给第四种作对比的，第四种方法对椒盐滤除效果很好。(Change the program package contains the value, mean filtering, adaptive median filter and an improved impulse noise filtering program is the first three compare to the fourth, the fourth method works well for removing salt and pepper.)

离散PID控制算法实例，matlab源程序(Discrete PID control algorithm instance, matlab source)

谱减法是一种比较简单的语音降噪的方法，在语音信号具有较高的信噪比的情况下具有良好的降噪功能。 (Spectral subtraction is a relatively simple pronunciation methods of noise in speech signal with high signal-to-noise ratio (SNR) of cases with good noise function.)

matlab程序：LFMCW雷达测速测距中CZT变换（输入为3个正弦信号）(matlab program：CZT transform of LFMCW Radar)

地球物理大地电磁测深的正演代码，包含了有限差分、有限元等(magnetotelluric 2D forward finite element program)

基于X12的季节调整模型的matlab程序(X12 seasonal adjustment model based on matlab program)

室内定位算法，指纹定位算法，几种不同的匹配算法(Indoor location algorithm, fingerprint localization algorithm, several different matching algorithms)

使用下面的参数设计信道均衡器，其中使用两个独立的随机数发生器，一个用x(n)来表示，用来测试信道；另一个用v(n)来表示，用来模拟接收器中的加性白噪声的影响。序列x(n)是x(n)=±1的伯努利序列，随机变量x(n)具有零均值和单位方差。第二个序列v(n)具有零均值，其方差由信噪比决定。均衡器有11个抽头。(Use the following parameter design of channel equalizer, which uses two separate random number generator, one with x (n) to indicate, to test the channel the other with v (n) to indicate to simulate the receiver in The additive white noise. Sequence x (n) is x (n) = ± 1 of the Bernoulli sequence of random variable x (n) with zero mean and unit variance. The second sequence v (n) has zero mean, its variance decision by the signal to noise ratio. There are 11-tap equalizer.)
