... into the random linear combi- nation process in conventional network coding. In network coding research, it is known that the higher the cardinality is, the more the benefits one may expect. Therefore, ... F q .Itis worth noting that the size of each f i remains equal to c j .We define the cardinality of f i to be the number of original data segments it contains, and the...
