说明：  M序列的调制 ，很好用 ，大家可以下来看看。(M sequence modulation, a very good use, we can look down.)

说明：  提供块和Python类以构建OFDM发送器和接收器 用于研究和教学目的，可动态配置的传输 参数。 包括基于Python Qt的可视化GUI。(Provides blocks and Python classes to build an OFDM transmitter and receiver for research and teaching purposes with dynamically configurable transmission parameters. Includes Python Qt based GUI for visualization.)

前后向平滑算法：算法的原理很简单，以五点三次平滑为例。取相邻的5个数据点，可以拟合出一条3次曲线来，然后用3次曲线上相应的位置的数据值作为滤波后结果。简单的说就是 Savitzky-Golay 滤波器 。只不过Savitzky-Golay 滤波器并不特殊考虑边界的几个数据点，而这个算法还特意把边上的几个点的数据拟合结果给推导了出来。(Before and after the smoothing algorithm: the principle of the algorithm is very simple, to 5.3 times smooth as an example. Take the adjacent five data points, you can fit out a curve 3 times, and then use the corresponding position on the third time the data value as the filtered results. Simply said is the Savitzky-Golay filter. However, the Savitzky-Golay filter does not specifically consider several data points of the boundary, and this algorithm also specifically to the edge of a few points of the data fitting results derived.)
