Kalman Filter Design

This is a program to study the dynamic instability of cylindrical shell due to parametric excitation.

Erasure correction achieved by two errors-only decoding passes using the Euclidean algorithm. Any (valid) code length can be input. (Erasure correction achieved by two errors- only decoding passes using the Euclidean algo rithm. Any (valid) code length can be input.)

三维fdtd的PML程序编写，少见的完全的版本(3D fdtd PML programmers, a rare complete version)

从电脑中选择一个图片，本程序可对图片完成类型转换，几何运算，代数运算（平均法降噪和减数运算），傅里叶变换，图像增强（包括灰度值变换，直方图均衡化，邻域平均法和中值滤波波法），图像复原，图像分割等功能。(Choose a picture from the computer, this program can complete type conversion, geometric operation, algebraic operation (average noise reduction and reduction), Fourier transform, image enhancement (including gray value transformation, histogram equalization, neighborhood averaging and median filtering wave method), image restoration, image segmentation and other functions.)

验证基于混合精度量化的大规模MIMO-OFDM系统的频谱效率的正确性。(The correctness of spectral efficiency of large-scale MIMO-OFDM systems based on hybrid precision quantization.)

通过计算短时信号熵，与阈值比较，得到判决结果。并采用顺序统计滤波器（最大值滤波器）对所得熵值滤波，提高判决精度。 能有效的分辨出语音信号和噪声信号，且通过后端平滑处理，使语音检测结果更加集中。(VAD based on short-time entropy, precision improved by using order-statistical-filter, VAD result is smoothed to make the result more accurate.)

说明：  离散信源无失真信源编码（实现huffman编码） 可用于教学(Discrete source lossless source coding (to achieve huffman coding) can be used for teaching)

频域采样理论是数字信号处理中的重要理论。要求掌握模拟信号采样前后频谱的变化，以及如何选择采样频率才能使采样后的信号不丢失信息( Frequency range sampling )
