Study on Blind Recognition of Binary Linear Block Code

As an important component of channel coding, （n, k） linear block code is widely applied in deep-space communication, satellite communication, wireless communication and other digital communication fields. Meanwhile, the blind recognition of （n, k） linear block code becomes increasingly prominent. Based on analysis of the characteristics and principles of （n, k） linear block code the math models of blind recognition are established, the length of block code, generator matrix, and parity-check matrix estimated, the recent achievements in this field summarized, and the advantages and limitations of various blind recognition algorithms concluded. Finally the future research on this blind recognition of binary linear block code is suggested in this paper.
