本文考虑了一个源节点网络，该网络使用随机线性网络编码，通过擦除信道通过中继节点向目标节点传输数据包。对于中继节点随机只给数据包的线性组合的系数赋非零值的情况，目标节点无法恢复所有源节点的数据包的概率在文献中已经被限定和近似。本文论证了当算术运算在较小的有限域上，如GF(2)时，有必要让中继节点也选择给系数赋零值。考虑了系数的替代概率质量函数，并重新推导了解码失败概率的表达式。
This paper considers a network of source nodes that transmit data packets to a destination node via relay nodes over erasure channels by using random linear network coding. The probability that the destination node will fail to recover the packets of all source nodes has been bounded and approximated in the literature for the case of relay nodes that randomly assign only nonzero values to the coefficients of linear combinations of data packets. The paper argues for the necessity of giving relay nodes the choice to also assign the zero value to coefficients when arithmetic operations are over finite fields of small size, e.g. GF(2). Alternative probability mass functions for the coefficients are considered, and expressions for the decoding failure probability are re-derived.
