The method includes code block segmentation is performed on a physical layer source data packet, to be sent, having a length of Ks bits, and channel coding is performed on each code block obtained by segmentation, to obtain Cs error-corrected and coded source data sub-packets having lengths of Kc bits; packet coding is performed on the error-corrected and coded source data sub-packets, to obtain Cp check data sub-packets; Ki codeword bits are selected from the ith sub-packet in Cs source data sub-packets, Kj codeword bits are selected from the jth sub-packet in the Cp check data sub-packets, all the selected bits are cascaded together to form a sequence having a length of formula (I), i=0, 1, . . . , Cs−1, j=0, 1, . . . , Cp−1, and the sequence is sent, herein Ks, Cs and Kc are integers greater than 1, and Cp, Ki and Kj are integers greater than or equal to 0.
