在MATLAB系统下的BP程序预测GDP(MATLAB system in BP procedures under the GDP forecast)

说明：  basic histogram equalization

MATLAB中GUI的设计实例，其中包括语音信号的录制、采样、滤波、重构、以及计算语音信号的频谱特性。(MATLAB GUI design example, including voice signal sampling, filtering, recording, and calculate the reconstruction, the speech signal spectrum characteristics.)

1. 图像二值化 2. 边界跟踪，去除离散点 3. 边界提取 4. 删除短边 5. 区分河流与道路 先找到桥梁，利用桥梁上的种子点 对道路进行跟踪，从而提取整条主干道。 (1 image binarization 2boundary tracking, removal of discrete points 3 boundary extraction 4 Remove the short side 5 distinguish rivers and roads the curvature is too large) First find the bridge, the bridge on the use of seed points on the road to follow, thereby extracting the whole trunk.)

信道的频率响应是时变的，设计最佳的固定的解调滤波是不可能的，因此，需要一种能补偿或减少接收信号中ISI的方法，这种ISI补偿方法称为均衡方法。 自适应均衡技术能够用来抵消由于信道带限或时间色散所导致的码间干扰，可以使通信系统更有效地利用信道带宽。 (Channel frequency response is time-varying, the best fixed design demodulation filter is impossible, therefore, need to be able to receive compensation or reduce the signal in the ISI method, the ISI compensation is called a balanced approach. Adaptive equalization techniques can be used to offset the channel band-limited or time dispersion caused by the inter-symbol interference can make communication systems more efficient use of channel bandwidth.)

说明：  应用matlab计算lamb波的频散曲线，计算群速度以及相速度。(Matlab computing applications lamb wave dispersion curves, group velocity and phase velocity calculation.)

对符号LMS算法进行性能仿真，并将其和LMS算法的 误差性能和收敛性能比较(The symbol LMS algorithm performance simulation, and error performance and LMS algorithm and convergence performance comparison)

说明：  利用matlab的gui设计的带有输入和输出功能的界面图形，可视性很强，自己独立编写的数据和图形，学习非常值得(Uses the Matlab GUI design to have the input and output function the interface graph, the visibility is very strong, the data and the graph which oneself compiles independently, the study is very worthwhile.)

有关雷达的使用的Matlab小程序，相当于雷达工具箱，特别是做雷达控制方面的很有用！(This project is very useful to the people who like doing the radar especially doing the radar control.)

该程序专门用于计算，金融证券估值计算股票期权的二项树过程。(The code can be used to plot generated binomial processes of stocks and options.)
