,用MATLAB实现快跳频通信系统的仿真。主要应用了SIMULINK和COMMUNICATION BLOCKETS两个模块。整个设计包括了信源产生部分、发送部分、跳频调制部分、信道部分、接收部分和结果分析部分共六个模块,核心技术是伪随机序列的产生和频率合成器的设计,而关键技术是收发两端的伪随机码元的同步。伪随机码的产生用S-函数编程来开发自己的SIMULINK模块。同步的实现是收发两端采用相同的扩频脉冲触发。而且在设计中每个模块都采用了模块封装技术,从而简化了框图结构(Using MATLAB to achieve fast frequency-hopping communication system simulation. The main use of SIMULINK and COMMUNICATION BLOCKETS two modules. The whole design, including part of the generated source, sending part of some frequency-hopping modulation, channel of the receiving part and the results of analysis of part of a total of six modules, the core technology is the emergence of pseudo-random sequence and frequency synthesizer design, and the key technology is the transceivers at both ends of the pseudo-random synchronization symbol. Pseudo-random code generated by S-function programming to develop their own modules SIMULINK. Synchronization is used to send and receive ends of the same spread-spectrum pulse trigger. But also in the design of each module using the module packaging technology, which simplifies the structure of the diagram)

tep 1:对遗传算法的运行参数进行赋值。参数包括种群规模、变量个数、交叉概率、变异概
率以及遗传运算的终止进化代数。
Step 2:建立区域描述器。根据轨道交通与常规公交运营协调模型的求解变量的约束条件,设
置变量的取值范围。
Step 3:在Step 2的变量取值范围内,随机产生初始群体,代入适应度函数计算其适应度值。
Step 4:执行比例选择算子进行选择操作。
Step 5:按交叉概率对交叉算子执行交叉操作。
Step 6:按变异概率执行离散变异操作。
Step 7:计算Step 6得到局部最优解中每个个体的适应值,并执行最优个体保存策略。
Step 8:判断是否满足遗传运算的终止进化代数,不满足则返回Step 4,满足则输出运算结果。
其次,运用遗传算法工具箱。(Matlab genetic algorithm toolbox)
