拉格朗日插值，本程序用拉格朗日插值公式对一元不等距观测数据进行程组插值 (Lagrange interpolation)

matlab 中具体OFDM过程，包含各种QAM调制方式，以及信道，编码，还有大量仿真图(OFDM matlab specific process, including various QAM modulation and channel coding, as well as a large number of simulation map)

利用matlab自带的一些程序，编写的一些滤波程序。包括线性平滑滤波、中值滤波、状态统计滤波等。(Matlab comes with some procedures, the preparation of some of the filtering process. Including linear smoothing filter, median filter, the state statistical filtering.)
