When extracting watermark data, error correction mode is adopted. 水印提取时采取纠错判决的形式,并实现了水印信息的盲检测。
In chapter 3, we introduce several commonly used error correction mode and its principle. 第三章我们介绍了几种常用的差错控制方式及其原理;
Existing systems commonly used serial communication. Different systems make different definitions of data format, transmission speed, transmission steps, error correction mode and control characters. The nonstandard communication protocol causes problems of poor compatibility. 现有系统普遍采用串行通信,不同的系统对数据格式、传送速度、传送步骤、纠错方式(ECM)以及控制字符定义等问题做出的规定并不统一,存在通信协议不规范、兼容性差的问题。
Then the components of NBDP equipment, encoding method, error correction technique and the two work mode ARQ and FEC are introduced respectively, in particular, the work principle and work process of ARQ and FEC in detail. 然后介绍了NBDP的设备组成、编码方式、检纠错技术和工作方式,特别对NBDP的两种工作方式即ARQ方式和FEC方式的工作原理和工作流程进行了详细阐述。
The error correction system that contains a multiple correction mode has been built based on technology mechanism, the device feature and different reasons that error arose from the soft measurement meters. 并从工艺原理和装置的生产特点入手,根据软测量仪表误差产生原因不同,建立了一个含有多重校正模型的误差校正系统。
