极化信道
说明: 极化码极化信道仿真,信道极化是信道合并与信道分裂两种信道操作的结果。在上述两种操作下,原本相同的N个W信道产生了极化现象,其中一部分信道的信道容量趋近于1,另一部分信道的信道容量趋近于0。(Channel polarization is the result of channel merging and channel splitting. Under the above two operations, the original n w channels have polarization phenomenon. The channel capacity of one part of the channel approaches to 1, and the channel capacity of the other part approaches to 0.)

基于AM335X平台的Ethercat实现.pdf
说明: EtherCAT(以太网控制自动化技技)是一种用于确定性以太网的高性能技业通信协议,它扩展了IEEE 802.3 以太网标准,使得数据传输中具有可预测性定时及高精度同步等特点。这个开放性标准作为 IEC 61158 的组成部分,常用于机械设计及运动控制等应用中。EtherCAT 采用标准的IEEE802-3 以太网帧,帧结构如图 1。EtherCAT 协议直接用标准以太网的帧格嵌传输数据,并不修改其基本结构(ethercat communication)
