matalab code for qam

一维灰度矩，用matlab进行编程，输入为一维灰度序列，输出为边缘值。不能直接处理图像！但有学习研究价值。(One-dimensional gray moment, using matlab programming for one-dimensional gray-scale input sequence, the output value for the edge. Can not directly deal with the image! But learning research value.)

使用matlab来比较4种不同的编码的性能。环境是BEC（删除信道）。 信号串的长度为2000(Use matlab to compare the performance of four different codes. Environment is the BEC (binary erasure channel). Length of the signal sequence is 2000)
