It is a madlab code for EDFA gain with length of optical fiber. Hope it will help to the students.

为了防止码间干扰，rs码编译码采用硬判决+维特比译码(rs_hdd_vterbi)

This source code shows in a simple way how we can conver a time domain signal to frequency domain signal by fast fourier transform.

采用bootstrap方法重抽样，可以将小样本变成大样本，适合乏信息问题(Resampling bootstrap method, small samples can be turned into a large sample suitable for lack of information problem)
