3 . error correcting cyclic redundancy checks based on confidence declaration is studied in detail 3 .详细研究了基于比特置信度判定的循环冗余校验纠错技术。
When binary checksums are used , 32 - bit redundancy check occurs on a column - by - column basis rather than a crc on the physical row on the data page 使用二进制校验和时, 32位冗余校验( crc )将逐列进行,而不是在数据页的物理行上进行。
Layer 2 frame cannot be processed by a receiver until all bits have been received by the receiver and a cyclic redundancy check ( crc ) has been performed 二层的帧必须等到所有比特全部接收通过crc (循环冗余校验)效验后才能被处理。
A layer 2 frame cannot be processed by a receiver until all bits have been received by the receiver and a cyclic redundancy check ( crc ) has been performed 二层的帧必须等到所有比特全部接收通过crc (循环冗余校验)效验后才能被处理。
( 4 ) cyclic redundancy check ( crc ) js a cyclic code often used redundancy information is added to every transport frame to detect the errors in it ( 4 )循环冗余校验crc码是常用的检测错误的循环码,通过在每个传输帧中加入冗余信息,而检出其中的错误。
Thedly , the method of cyclic redundancy check ( crc ) in system softwar design was used to ensure the serial conununication reliability betwen contactless ic card and reader 第三,在系统软件设计中采用crc校验码检错、出错重发相结合的方法确保非接触ic卡与读写器串行通讯可靠。
In this paper , we discuss about the theory of cyclic redundancy checks and its application . we take dsi 820 for example to realize the hardware and software methods in dallas ' s 1 - wire chips 讨论了crc校验原理及在单总线中的应用和实现方式,以ds1820为例分别用硬件和软件编程实现了单总线上的crc校验。
Its additive device performance means full bandwidth to each drive . sata cabling provides scalability , hot - plug connections mean quick drive replacement , and cyclical redundancy checking builds toughness Sata布线提供了可扩展性热插拨连接实现了硬盘的快速更换而循环冗余码校验crc则保证了产品的牢固。
According the product code scheme proposed in nsfc projects , in that scheme , the product code has a special structure and uses the cyclic redundancy check ( crc ) to detect whether the information is decoded correctly 依据课题所研究的乘积编码,利用其特殊构造,使用循环冗余校验作为译码是否正确的判决,从而使乘积编码的行列交替约束,实现约束维特比译码。
Firstly , the discrete multi - tone processing in an adsl central office - side interface card is detailedly introduced . the processing mainly includes timing , framing , interleaving , forward error correction , cyclic redundancy check , constellation encoding , inverse fast fourier transform processing , prefixing , d / a converting , and amplifying . secondly , a kind of interface named utopia level 2 is used as the network interface , with which many adsl devices are linked with one atm layer 本文比较详细地阐述了数字用户线接入模块( dslam )开发方案中, adsl局端接口模块的dmt编码与调制过程,讨论了其组网应用方式以及基于atm的网络侧接口utopia2技术,分析了adsl与其它宽带接入技术的相互联系和优缺点,并介绍了方案中所采用的一些关键技术,包括在线插拔技术、系统同步启动和故障自动重起技术以及高速数字信号完整性的保证技术等等。
