LDPC pexit图分析
原模图分析译码门限值时,传统的EXIT不能用,所以采用pexit图,是原模图分析的最重要的工具。文中提出了一种新的外部信息转移分析方法,主要针对基于原模图和多边形的LDPC码 ,进一步介绍了边连接的限制,对于这一类的许多类型的码字,传统的EXIT图分析方法不能应用,文中提出的PEXIT图考虑了边的连接,允许对基于原模图的LDPC码的译码收敛估计,允许设计高结构化的接近容量的LDPC码

I2C通信,verilog语言
I2C 通信中只涉及两条信号线,即时钟线 SCL 和数据线 SDA。时钟线为高电平时均可锁存数据(即时钟线上升沿到下降沿之间)。当时钟线 SCL 高电平时,如果把数据线 SDA 从高
电平拉到低电平,则表示通信开始;如果把数据线 SDA 从低电平拉到高电平,则表示通信结束。
代码中分了两个模块,iic_com 模块除了执行和 I2C 通信有关的代码设计外,还有按键检测部分,而 led_seg7 模块只是驱动数码管显示从 AT24C02 指定地址读出的数据。
