天线实频匹配法优化函数的构造，可扩大频带宽度,达到提高增益的效果(the function structure of the real frequency method)

说明：  基于MATLAB的直接序列扩频的研究与仿真代码(MATLAB-based direct sequence spread spectrum code and Simulation Study)

MATLAB 软件是当今控制系统的设计与仿真中重要的工具软件。该软件仿真方便， 结果直观、准确。本文以单相桥式全波可控整流电路及三相桥式全波可控整流电路为例，叙 述了利用 MATLAB/SIMULINK对整流电路进行建模仿真的方法，并给出了仿真结果波形。 通过对仿真结果分析就可以将系统结构进行改进或将有关参数进行修改使系统达到要求的 结果和性能，这样就可以极大地加快系统的分析或设计过程。 (MATLAB software is the current control system design and simulation of the important tools. The software simulation convenience, the results of direct and accurate. In this paper, single-phase full wave controlled rectifier bridge and three-phase full wave controlled rectifier bridge, for example, describes the use of MATLAB/SIMULINK model of the rectifier circuit simulation method, and gives the simulation results waveform. Through the simulation results of the system structure can improve or modify the relevant parameters of the system to achieve the required results and performance, so that you can greatly speed up the system analysis or design process.)
