摘要： A transmission system may include a transformer, an adder, an encoder, and a transmitter. The transformer may segment and transform a data packet into segments. The adder may add a check code to each of the segments. The encoder may encode error correction to each of the segments with the added check code. A receiving system may include a receiver, a decoder, a checker, and a selector decoder. The decoder may decode error correction in each of the encoded segments. The checker may check the check code of the error corrected segments. The selector decoder may select at least one of the valid segments based upon the check code and transform the selected segments into a data packet.
