Abstract:
1. A random linear network coding method implemented by a transmitting end, comprising: splitting, by the transmitting end, original data into at least two data blocks sequentially; determining, by the transmitting end, at least two coefficient groups, wherein a length of each coefficient group is the same as the number of the data blocks, wherein each coefficient group comprises two elements, and wherein the two elements in the coefficient groups comprise 0 and 1; performing, by the transmitting end, a bitwise-AND operation on the data blocks and coefficients corresponding to the data blocks to obtain code blocks; performing, by the transmitting end, a bitwise-XOR operation between the code blocks to obtain a code packet; and setting, by the transmitting end, an average number “K” of non-0 coefficients in all coefficient groups before determining the at least two coefficient groups.
