| 摘 要： | 在高速数字通信网络中,由于噪声干扰、瞬时中断等原因,导致信号在传输过程中不可避免地会产生误差.为了确保数据在传输过程中的可靠性,可在数据传输过程中引入差错控制策略来检查和纠正差错.循环冗余校验码是目前被广泛采用的错误校验编码,分析了基于循环冗余检验码的反馈重发式差错控制策略,给出了采用硬件和软件分别实现循环冗余校验的可靠途径.

| Abstract: | In high-speed digital communication networks,due to noise interference,instantaneous disconnection and other kinds of reasons,the signal inevitably produces errors during transmission.In order to ensure the reliability of the data during transmission,so an error control strategy was introduced to check and correct the errors during the course of transmission.CRC(cyclic redundancy check) is widely used as error-correction coding in recent.A Go-Back-N error control strategy based on the cyclical redundancy ch... |
