摘要
自动重传请求(ARQ)机制是一种实现无线通信节点之间信号可靠传输的技术。探讨了ARQ机制的3种实现方式,详细描述了将连续ARQ运用在应用层,在嵌入式操作系统VxWorks下实现的文件可靠传输设计。介绍了系统的设计背景、设计实现,并讨论了如何优化设计从而提高传输效率和信道利用率。设计具有较强的通用性,可广泛运用在要求大数据量可靠传输的场景。
Automatic Repeat request （ARO） mechanism is a kind of technology to realize reliable transmission in wireless communication. The paper discusses three implementation methods of ARQ mechanism with the emphases on continuous ARQ. Base on this, the reliable file transmission is realized in embedded operating system VxWorks. This paper also discusses how to make fiall use of channel resource by optimizing design. The project can be applied to the scene requiring reliable mass data transmission.
