用matlab编写的比较全面的关于非线性光纤中孤子演化的程序(Matlab prepared with a more comprehensive on the nonlinear optical soliton evolution in the process)

用单纯形法求解线性规划 用完整单纯形法求解线性规划 用修正单纯形法求解线性规划 (Complete simplex method for solving linear programming using the simplex method for solving linear programming using the revised simplex method for solving linear programming)

Spread spectrum merupakan sistem dimana sinyal yang dikirimkan memiliki bandwidth yang jauh lebih lebar daripada bandwidth sinyal informasinya sendiri. Proses pelebaran bandwidth sinyal informasi ini dilakukan pada sisi pengirim dan disebut spreading. Sebaliknya, proses penyempitan kembali bandwidth sinyal informasi dilakukan di sisi penerima, dan disebut despreading. Pada gambar 1 berikut menunjukkan proses yang terjadi pada sistem spread spectrum.

不考虑模态耦合项的多阶模态力法，是楼文娟文章中的程序(Without considering modal coupling term multi-modal legislation, LOU Wen-juan article in the program)

本程序实现了一个基本的基于2psk的误码率仿真程序，比较适合初学通信的人士学习。(This program realize a simulation based on Bpsk modulation, and it is suitable for any beginner of telecommunication)
