基于DVB-T标准,COFDM调制系统的利用导频信号进行符号粗同步,仿真条件：68个OFDM符号，64QAM调制，莱斯信道(Based on DVB-T standard, COFDM modulation system using pilot symbols rough signal synchronization, simulation conditions: 68 OFDM symbols, 64QAM modulation, Rice channel)

说明：  原理：以待处理的像素作为中心，取一个nXn的模板，在模板中选择k个与待处理像素的值最接近的像素，将这k个像素的均值替换原来的像素值。 假设n=3，k=5，调用方法：b = KNNMeanFilter(a, 3, 5)(Principle: to be treated as the center pixel, take a nXn template select the template and the pending k-nearest pixel values of pixels, this k pixels mean replacing the original pixel value. Assuming n = 3, k = 5, call the method: b = KNNMeanFilter (a, 3, 5))

A program to generate the following with the help of input length sequence. 1. Unit impulse function. 2. Unit step function. 3. Unit ramp function. 4. Exponential function.

有关卡尔曼滤波的文档，很有用处，大家传阅这看吧！！！！！！！！！！！！！(about kalman filter)
