AUTOENHANCE Automatically adjusts/enhances the image(brightness, color and contrast) to "optimum" levels.

建立了整车的6自由度模型，包括轮胎模型、车身模型、垂向力模型等(The 6DOF model of vehicle)

模糊PID控制器优化函数的文章，很不错的，很有参考价值，是英文版的可以作为参考资料。(Fuzzy PID controller optimization function article, very good, good reference is the English version can be used as reference.)

The channel estimation algorithm is based on a subspace approach. The method works only for identifiable STBCs (excluding >=1-rate STBCs). See publication [1] for more detail about the algorithm and the identifiability conditions. The zip file contains three m files. - space_time_coding.m (perform space time coding) - subspace_channel_estimation_STBC.m (channel estimation) - one_shot.m (show an example) To use these files, extract the three files in the same folder. Then, call the script one_shot in the matlab command window. Reference: [1] Ammar, N. Ding, Z.
