AB  - Early stopping belief propagation (ESBP) decoding schemes reduce the decoding complexity by stopping decoding iteration when a predefined stopping criterion is satisfied. However, ESBP decoder still has higher decoding complexity compared to the successive cancellation decoding schemes. In this paper, we propose a partial early stopping scheme to reduce the decoding complexity of the G-matrix based ESBP decoder by speculating Hamming distance between reencoded and hard decisioned received codewords. With the proposed scheme, the decoding complexity can be reduced without any performance loss.
