matlab下实现降噪，功率谱计算。％程序中设定采样点数为256个，采样频率为10000hz， ％输入信号为随机噪声和两个正弦的合成信号 ％设定的滤波器的截止频率为3500hz ％通过挈比雪肤滤波器，运行程序，比较滤波前后的频域波形 ％滤波去除了高频信号(matlab achieve noise reduction, power spectrum calculation. Sampling procedure set for 256 points, the sampling frequency of 10000hz, input signal for the random noise and the two sinusoidal signals synthetic filter set a cut-off frequency 3500hz manner than through the filter雪肤, run procedures, compared before and after filtering in frequency domain waveforms filtering in addition to high-frequency signals)

这是一个纯MATLAB编写的俄罗斯方块的游戏。游戏非常的简单，只需上下左右四个键就能操作。算法较为精炼，值得参考。(This is a matlab code about RussionBlock. It s easy and useful. It worth your time on it.)

这是一个基于空时分组编码的MIMO_OFDM通信系统的仿真设计。此系统包括QPSK调制解调，IFFT调制，空时编解码，基于训练符号的信道估计等通信模块。希望对大家有帮助！ (This is based on the space-time block codes of MIMO_OFDM communication system simulation design. This system includes QPSK demodulation, IFFT modulation, space-time decoding, based on the training symbol of channel estimation and other communications module. We want to help!)

这是接着上一次的一些大家很可能用到的聚类分析方法，有PCA等，希望能给大家一些帮助。(then this is the last time some people may use the cluster analysis method, PCA. I hope that it provides some help.)

这段代码主要用于工程中的结构有限元设计，依次从代码中很容易求解出结构所划分的节点数，单元数以及荷载等。(This code is mainly used for finite element in structural engineering design, are easily solved by the number of nodes in the structure of the number of units, and load.)

介绍了在多通道下的多普勒频移解决方案，能很好的解决实际多径频移问题(Describes the multi-channel Doppler frequency shift under the solution, can be very good to solve practical multi-path frequency-shift problem)

原始lmd算法，效果很不好，不知道程序哪里写错,不太能运行，自己做修改，但是上面的算法比较明确(The original LMD algorithm, the effect is very bad, I don t know where the program is misspelled,but it really can not run.If you want run it,just change a little.Actally the algorithm is clear.)

Matlab关于数学和物理问题的27种示范应该和解析，详细，并有程序解释，不可少的专业书啊，特别适合数学和方面的人！(Matlab mathematical and physical problems on the 27 model and should be resolved in detail, and explain the program, essential for professional book ah, especially for mathematics and in person!)

使用交互式算法比较单传感器和多传感器融合的性能。(Interactive algorithm compared with single-sensor and multi-sensor fusion performance.)
