通信系统仿真 #实验目的 这是一个综合性的大型实验,通过搭建一个包括信源、信源编译码器、信道、信道编译码器等各模块在内的仿真通信系统, 使学生能够加深对本课程各个重点章节的理解,更好地掌握通信的本质意义。 说明: 由于搭建一个完整通信系统的工作量较大,所以本实验可以使用Matlab等仿真工具。下面分别描述系统中各个模块的要求。本程序只使用了java 离散信源:要求能以指定的概率分布(p,p-1)产生0,1符号构成的二进制信源符号序列。 信源编码器:输入时上一步产生的二进制符号序列。要求能选择以下三种中的任意一种 1.无编码(直通) 2.二进制香农-费诺编码 3.二进制霍夫曼编码 当我们在上一步中指定信源的概率分布之后,就可以马上生成这几种编码的码表,实际的编码工作仅仅只是查表而已。 当然,直接对上一步指定的信源进行编码是不合适的,需要先进行信源的扩展,换一句话说,需要确定信源分组的长度。
