中文摘要：

针对随机线性网络编码，提出点一点检错和端一端重传相结合的差错控制方法．借助于随机线性网络编码的鲁棒性，对信道的突发性错误和随机错误，采用三维奇偶校验码进行检错，让有错的数据包不参与编码；当宿点不能解出源点播出的信息时，通过反馈重传策略让源点重传信息．理论分析和仿真测试结果表明，在伽罗华域较大且数据包较长时，提出的方法能以较大的概率消除信道的传输错误，并解决了全局编码向量出错的问题，且以较低的重传率实现宿点完整地接收源点的信息．

英文摘要：

Aiming at random linear network coding, this paper proposes an error control method which combines point-point checking error and end-end retransmission. By virtue of the robustness of random linear network coding, this method adopts three dimensional parity checking code to implement point-point checking error, and let erroneous packets not take part in coding. When a sink node can not decode the information coming from source node, it transmits feedback information to source node to request retransmission. Theoretical analysis and simulation results show that, by using larger Galois field and larger packet, the proposed method has high probability to eliminate transmission error including global network coding vertexes error, and make sink nodes integrally receive information from source node at lower retransmission rate.
