说明：  OFDM的系统仿真，使用TCM编码，维特比译码。可以绘出多径延时状态下的不同信噪比的误码曲线(OFDM system simulation, the use of TCM coding, Viterbi decoding. Multipath delay can be drawn under the error curves of different signal to noise ratio)

这个程序主要是对车牌定位相关的东西进行了编程，希望有所帮助。(This program mainly for license plate location was something related to programming, want help.)

训练错误率和交叉验证错误率相等，在样本比较大时，这个结果是可以预期的；训练错误率一般低于测试错误率，但是当样本数据比较少时，实验也出现了意外，样本多的那组测试错误率比样本少的训练错误率还要小；在本实验中，同组数据的交叉验证错误率比独立测试错误率高，这个反常现象是因为样本的原因所致，交叉验证的样本小，而独立测试时所用训练样本数目大，因而出现这种情况。分类线上，fisher准则是一条直线，而贝叶斯分类器实际上是一个类似椭圆的封闭曲线；很明显，贝叶斯分类器比fisher分类器要好。(Training error rate and cross- validation error rates are equal, the larger the sample , this result is to be expected training error rate is generally lower than the test error rate , but when comparing the sample data came from the experiment there was an accident, that more samples group test error rate less than the training sample error rate is smaller In this experiment, the same set of data cross-validation error rate than independent test error rate, this anomaly is because the sample of reasons , cross-validation sample is small,And independent testing large number of training samples used , resulting in this situation.Classification online , fisher criterion is a straight line , while the Bayesian classifier is actually a closed curve similar to elliptical It is clear that the Bayesian classifier is better than the fisher classifier .)

除趋势波动分析，非常好的分析工具。除趋势波动分析，非常好的分析工具(distrend fluctuation analysis, very good analysis tool)

这是基本的脚点检测算法，里面包含了harris detector和harris-laplace detector code，便于操作。(This is the basic foot-point detection algorithm, which includes harris detector and harris-laplace detector code, easy to operate.)

gm(1,1)灰色预测模型，可以进行各种预测。短期的电力负荷预测尤其的好。也可以进行中长期的预测，但是效果没有短期的好。(gm (1,1) Grey forecasting model can predict all kinds. Short-term load forecasting particularly well. Can also make long-term forecast, but they were not short of good.)

粒子群算法，类似于遗传算法工具箱的调用语句(pso code)

信号SVD去噪，采用FFT变换，达到信号去噪的作用(SVD signal denoising, FFT, signal denoising role)

瑞利分布杂波幅度和高斯谱仿真，需要的可以学习看下(Rayleigh distribution clutter simulation, the need to learn a look)
