Abstract: In one exemplary embodiment of an apparatus for accelerating the encoding of Raptor codes, based on an inputted block length, a pre-encoding matrix generation device determines to generate an encoding matrix M corresponding to the inputted block length and computes an inverse matrix M?1, or makes a pre-coding operation list storage device output an operation list corresponding to the inputted block length; based on the encoding matrix or the inverse matrix M?1, a pre-encoding operation list generation device generates a new operation list; based on one of the aforementioned two operation lists and an inputted source symbol set, at least one prompt intermediate symbol generation device generates at least one intermediate symbol set to provide to a fountain code encoder for encoding.
