BCH Based U-UV Codes and Its Decoding

This paper proposes the U-UV structured codes with BCH codes as its components. This coding construction will lead to polarized subchannels and rate of each component code can be designed accordingly. The component code will be decoded by the ordered statistic decoding (OSD), yielding multiple decoding outcomes. Integrated in a successive cancellation (SC) decoding mechanism, SC-list (SCL) decoding of the U-UV codes is further proposed. Our simulation results will show that over the short-to-medium length regime, SCL decoding of a BCH based U-UV code can outperform that of a similar rate polar code.
