计算光纤模场分布和传播常数，输入模式的阶数，计算得到各类模式的模场分布。直接运行main，在其中修改参数，至少可以计算5层光纤结构。...

说明：  基于pareto的多目标遗传算法，它是NSGA2(Pareto-based multi-objective genetic algorithm, which is NSGA2)

说明：  由于阵列处理中常常需要对接收信号进行分析，MUSIC算法是其中最为经典的(As the array processing is often necessary to analyze the received signal, MUSIC algorithm is one of the most classic)

本程序用于OFDM基本原理，仿真数据调制采用QPSK(This procedure is for OFDM basic principle, the simulation data modulation method is QPSK )

为感谢惠俊英老师的谆谆教诲，特为好奇诸君奉上水声物理--海洋传播声场模拟的一份武林秘籍！ 当好奇诸君阅毕此卷，再对照轻松跑完六份作业（六路招式），即入“水声物理”之江湖！ BELLHOP与AcousticsToolbox遵照GNU公共许可证进行分发。感谢Michael B. Porter对BELLHOP的原创，也感谢Orlando Camargo Rodríguez此份大道至简的入门秘籍。更感谢由Free Software凝聚起来的自由科学家社区。(Bellhop is a highly efficient ray tracing program, written in Fortran by Michael Porter as part of the Acoustic Toolbox (available at the website of the Ocean Acoustic Library). Bellhop is designed in order to perform two-dimensional acoustic ray tracing for a given sound speed profile c(z) or a given sound speed field c(r; z), in ocean waveguides with flat or variable absorbing boundaries. Output options include ray coordinates, travel time, amplitude, eigenrays, acoustic pressure or transmission loss (either coherent, incoherent or semi-coherent).)
