摘要

Intuitively, for polar decoding, an accurate signal-to-noise ratio (SNR) estimation is necessary when using belief propagation (BP) polar decoders. It has been claimed in literature that the BP decoding is sensitive to SNR underestimation. However, there are two kinds of BP decoders, the conventional BP and “min-sum (MS)” based BP, adopted in practice. In this paper, an investigation toward SNR se...
