Abstract :
In this paper, the tail-biting version of the low-density parity-check convolutional codes (LDPCCCs) is introduced and investigated. The definition of the tail-biting LDPCCCs (TB-LDPCCCs) is given through their parity-check matrices and the basic ideas behind the architectures of the encoders and decoders for these codes are also presented. In addition, the asymptotical lower bound for the minimum distance of these codes and simulation results are shown.
