基于Matlab7_0PDE工具箱求解数学物理方程。直接应用Matlab7.0 的偏微分方程工具箱求解数学物理方程的方法(Based on equations of mathematical physics to solve Matlab7_0PDE toolbox. Matlab7.0 direct application of partial differential equations of mathematical physics equation solving toolbox approach)

求jeffcott转子模型的临界转速的matlab编程(Seeking jeffcott critical speed of the rotor model matlab programming)

The Communications Blockset is a collection of Simulink® blocks for designing and simulating communications systems. With the Communications Blockset, you can design models in the form of block diagrams, using simple click-and-drag mouse operations. You can run simulations on a model at the push of a button, and change parameters while the simulation is running.

定时恢复在接收机中是必不可少的环节，只有定时恢复环节性能良好才能正确解调出信号。 位同步-gardner算法(Timing recovery is an essential part of the receiver, and the signal is demodulated correctly only when the timing recovery is in good performance.)

用matlab作图时，对于下标的标注格式需要用特殊符号来实现。本文档里面归纳了相关的标注格式的符号，供大家学习参考。(Plotted using matlab need to use special symbols for subscripts label format. This document which summarizes the annotation format symbols, for all to learn.)
