ssb modulation and demodulation for three tone signal

这是一种导频辅助的径向线性插值信道估计算法，算法来自于12年3月份的IEEE,画出比特信噪比与误码率的关系曲线.(This is a polar-linear lnterpolation aided channel estimation algorithm，which comes from IEEE in march 2012,drawn-bit signal to noise ratio and bit error rate curve.)

数值计算-插值【matlab例程】经典算法直接应用方便快捷(Numerical calculation- interpolation routines] [classical algorithm matlab convenient direct application)

说明：  假如数据中有N 个变量，而我们想抽取的样本的数量是M,那么在对数据进行抽样的时候，这种方法首先会把N个变量的设计空间均匀的划分开为M份，然后在每个划分好的区域中随机的抽取一点，最后，从这M个变量里，随机挑选之前选好的点，构成我们的样本(If there are n variables in the data, and the number of samples we want to extract is m, then when sampling the data, this method will first divide the design space of n variables into M parts evenly, and then randomly extract a point in each divided area. Finally, from the m variables, randomly select the previously selected points to form our sample)
