An ensemble of LDPC convolutional codes with parity-check matrices composed of permutation matrices is introduced. The convergence of the iterative belief propagation based decoder for terminated convolutional codes in the ensemble when operating on the erasure channel is analyzed. The structured irregularity in the Tanner graph of the codes leads to significantly better thresholds when compared to the corresponding LDPC block codes.
