Low-density parity-check convolutional codes (LDPC-CCs) are generally decoded using sliding- window based message passing decoding. Based on the sliding-window decoding, an informed dynamic scheduling (IDS) for LDPC-CC is proposed in this work, where the decoding convergence can be significantly accelerated. Since the number of processors required for a satisfactory performance can be reduced, the decoder can be simplified. A set of rate-compatible (RC) puncturing patterns is also proposed and is used to construct RC LDPC-CCs for the performance evaluation of the proposed IDS. Although the proposed puncturing pattern cannot be optimized for individual code rate owing to the rate-compatible constraint, they can still provide a comparable error rate performance compared to the codes defined in the IEEE 802.16m standard. It is worth noting that these standard codes are not rate-compatible.
