Abstract
The channel coding blind identification technology identifies the channel coding parameter by analyzing the coded data, then realizes the breakthrough from signal layer to information layer, which is widely used in signal monitoring, information acquisition, intelligent communication and other fields. This paper proposes a parity-check matrixbased F-LDPC codes parameter identification method by studying the F-LDPC codes coding mechanism and parity-check matrix generation principle, which can identify the repeat parameter and the puncture parameter of F-LDPC codes according to the parity-check matrix weight characteristics, and recover the equivalent random interleaving of FLDPC codes according to the parity-check matrix structure characteristics. The simulation results show that this method can achieve the recognition of the repeat parameter, the puncture parameter and the random interleaving of regular F-LDPC codes under the condition that the complete parity-check matrix is known.
