这是一个matlab的源程序，只要打开就知道了，具体我久不说了谢谢大家！(This is a matlab source, as long as the Open will know the specific久不I said thank you!)

说明：  OFDM全系统仿真代码，包括卷积编码，调制解调，四倍过采样(OFDM system-wide simulation code, including the convolution coding, modulation and demodulation, four times oversampling)

用窗函数法设计FIR数字滤波器，能熟悉矩形窗、海宁窗、汉明窗和布莱克曼窗。掌握用上述窗函数法设计FIR数字滤波器的原理和方法。熟悉线性相位FIR数字滤波器特性。了解各种窗函数对滤波特性的影响。 (FIR window design with a digital filter function can be familiar with the rectangular window, Haining window, Hamming window and Blackman window. Master window function with the FIR digital filter design theory and methods. Familiar with linear phase FIR digital filter characteristics. Learn a variety of window function on the filter characteristics.)

卡尔曼滤波评估，用于精密单点定位,提高了定位精度，在某工程上已经得到验证(Kalman filter evaluation for precise point positioning, positioning accuracy has been verified on a project)

这种方法一方面将像素的灰度值分散，可以分辨图象中比较细节的内容；另一方面，将图 象的灰度变化控制在一定范围之内，抑制了噪声的产生，较大程度上地保留了原始图象的亮度．(This approach on the one hand spread the pixel gray value, the more details you can identify the contents of the image the other hand, the image gray scale control in a certain range, suppress noise generation, a greater degree preserved on the original image brightness.)
