- ,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

扩频系统通信仿真
- 扩展频谱通信系统是指待传输信息的频谱用某个特定的扩频函数扩展后成为宽频带信号,然后送入信道中传输,再利用相应手段将其解扩,从而获取传输信息的通信系统。它在传输同样信息时所需的射频带宽,远比大家熟悉的各种调制方式要求的带宽要宽得多。扩频前的信息码元带宽远小于扩频后的扩频码序列的带宽,信息己不再是决定调制信号带宽的一个重要因素,其调制信号的带宽主要由扩频函数来决定。一般常用的扩频函数是伪随机编码信号。与常规的通信系统相比,扩频系统具有很强的抗人为干扰、抗窄带干扰、抗多径的能力,此外还具有信息隐蔽多址
