| 中文摘要:为提高无线网络编码数据包传输效能，提出了基于时间复杂度的无线网络编码数据包平均传输次数优化方法。首先分析无线网络编码数据包传输信道的多径特性，并根据数据包的多径特性采集有效且安全的数据包，同时在IEEE802.3EFM通信协议下构建数据包的传输信道模型。为提升数据包的传输及存储性能，需建立缓存反馈机制，在该机制作用下设计混合编码。最后采用自适应量化融合编码的方法，进行无线网络编码数据包传输的调制解调处理，结合时间复杂度的衡量算法实现无线网络编码数据包传输的传输次数优化，提升了无线网络混合编码下数据包的传传输效能。仿真结果表明，采用该方法进行无线网络编码数据包传输的输出均衡性较好，传输误码率较低，时间开销较短。 |

| Abstract:In order to improve the transmission efficiency of encoded packets in wireless networks，an optimization method of average transmission times of encoded packets in wireless networks based on time complexity is proposed. Firstly，the multi-path characteristics of wireless network coding data packet transmission channel are analyzed，and effective and safe data packets are collected according to the multi-path characteristics of data packets. At the same time，the transmission channel model of data packets is constructed under IEEE802.3EFM communication protocol. In order to improve the transmission and storage performance of packets，it is necessary to establish a cache feedback mechanism. In this mechanism，the hybrid coding is designed. At last，the adaptive quantization fusion coding method is used to modulate and demodulate the wireless network coding data packet transmission. The transmission times of the wireless network coding data packet transmission are optimized with the time complexity measurement algorithm，which improves the transmission efficiency of the wireless network mixed coding data packet. The simulation results show that the output balance of wireless network coding packet transmission is good，the transmission error rate is low，and the time cost is short. |
