摘　　要：数据在传输过程中由于多线程同步或者缓冲区溢出等问题经常发生丢包的问题,为改进该问题,本文提出基于HARQ协议的传输方案,该协议发送方根据接收方反馈的信道状态调整数据包集大小。通过搭建的数据传输平台进行了验证,在传输距离为80 m时,误码率为0%;丢包率为10%时,信道输出率提高了14.5%。该传输方式在降低了因反复重传数据所造成的带宽损耗时也保证了接收的数据完整正确,真正提高了高速串行总线接口传输的可靠性。In the process of data transmission packet loss often occurs due to problems such as multi-thread synchronization or buffer overflow.To improve this problem this paper proposes a transmission scheme based on HARQ protocol where the sender adjusts the set size of the data packet according to the channel state fed back by the receiver.The data transmission platform is built and verified.When the transmission distance is 80 m the bit error rate is 0%.When the packet loss rate is 10%the channel output rate is increased by 14.5%.The transmission mode ensures that the received data is complete and correct when the bandwidth loss caused by repeated retransmission of data is reduced and the reliability of the high-speed serial bus interface transmission is truly improved.
