Is a good learning routines!)

利用Matlab分别生成OFDM信号和短波信道仿真器(OFDM signals and shortwave channel simulators are generated using Matlab respectively)

The objectives of Partial Differential Equation Toolbox™ software are to provide you with tools that: • Define a PDE problem, e.g., define 2-D regions, boundary conditions, and PDE coefficients. • Numerically solve the PDE problem, e.g., generate unstructured meshes, discretize the equations, and produce an approximation to the solution. • Visualize the results.
