如何利用遗传算法工具箱函数编写求解实际优化问题的MATLAB程序(how to use genetic algorithm toolbox function optimization prepared to solve practical problems MATLAB)

说明：  卡尔曼滤波，对一组数据滤波。也可以自己修改针对矩阵形式(Kalman filter, a set of data filtering. You can make changes to the form for the matrix)

实现OFDM误码率曲线图的仿真,打开MATLAB软件，直接运行OFDM.M的那个文件就可以了(very good)

this is a source code about neural networks

考虑L的三个不同值：L＝256（3个数据段），L＝128(7个数据段)和L=64（15个数据段）。各自的谱估计图如上图所示。可以明显的看到，加窗明显的减小了频谱上的假谱峰，但也更加进一步平滑了谱峰。所以，对于L＝64的情况，在ω＝0.8π的谱线可以很确定的辨认，但是那两个靠近的谱峰不容易区分。对于L＝128的情况，这种情况提供了在分离和检测间最好的均衡。当然，对于在L＝256时的情况，效果是更好的，能够从谱估计图上明显的分辨出三条谱线的存在以及它们幅度关系的强弱。 除了Welch法外，还可以采用对多个周期图求平均的功率谱估计方法的其他方法如Bartlett法等等，在功率谱估计上也能取得较好的结果。(consider three different values : L = 256 (3 data), L = 128 (7 data) and L = 64 (15 data). Their spectral estimation map as shown in Fig. It is clear to see that increase significantly decreasing window of the spectrum of false peaks, but much more to further smooth the peaks. Therefore, L = 64, in the case = 0.8 spectrum can determine the identification, but that the two peaks around is not easy to distinguish. L = 128 for the situation, which provided the separation and detection among the best balanced. Of course, L = 256 in the case, the effect is better, from the spectral estimation map clearly distinguish between the three lines of the existence and their relationship to the rate of strength. In addition to Welch law, but also can be used to map multiple cycle for the average power)

关于matlab学习的电子教案，基本的学习资料。(E-learning lesson plans on matlab, basic learning materials.)
