Thus, we proposed VoIP traffic tolerance mechanism, which allow voice frame with error pass CRC check to reduce unnecessary retransmissions, finally improve QoS of VoIP traffic. 为此,论文提出了VoIP业务容错机制,对VoIP业务在MAC层进行容错处理,忽略CRC校验,减少不必要的重传,提高VoIP业务的总体服务质量。
When no error happens in transmission, only CRC check is executed, while complicated BCH code is avoided, so the processing energy of sensor node is saved. 在信息传输无误码的情况下,只调用CRC校验,避免了复杂的BCH译码,节省了传感器节点的处理模块能量消耗;
Some error checking method commonly used in GPS data communication are analyzed in this paper such as sum check and Cyclic Redundancy Check, detailed calculation realization is also given in C language. 本文针对GPS数据通讯中目前常用的校验和校验以及循环冗余校验(CRC校验),从校验原理入手,具体给出其计算方法和C语言实现。
Cyclic Redundancy Check ( CRC ) code and the principle of error checking / correction commonly used for safe information transmission in urban mass transit are analyzed. 分析城市轨道交通安全信息传输中常用的循环冗余校验(CRC)的编码和检纠错原理。
The cyclic redundancy check ( CRC ) is an error inspection code widely applied. 循环冗余校验(CRC)就是一种被广泛采用的错误检验编码。
