SISO Decoding of U-UV Codes

U-UV structural coding with algebraic component codes can provide competent error-correction performance in the short-to-medium length regime. Constituted by BCH component codes and its ordered statistics decoding (OSD), the successive cancellation list (SCL) decoding of U-UV codes can outperform that of polar codes. However, the current SCL decoding is a soft-in hard-out (SIHO) process. Exploiting its list decoding feature, this paper proposes a soft-in soft-out (SISO) decoding for U-UV codes, providing the key technique for the codes to be further engaged in an iterative system. The proposal is designed based on the recursive structure of U-UV codes and the list decoding feature for both the component and the structural codes. Both the decoding complexity and its soft information transfer characteristics are also shown.
