Polar code is adapted as the channel coding scheme for control channel in 5G NR. The basic algorithm of polar code is the successive cancelation (SC) decoding but its performance is not good enough and decoding latency is relatively high. So the simplified successive cancelation list(SSCL) decoding is generally used. When the SSCL is operated, path metric calculator generates children candidates and the number of children candidates influenced on the H/W complexity. The reliability of children candidates is affected by that of their parent candidates. The number of children candidates is adaptively selected according to the reliability of their parent candidate and the total number of children candidates could be reduced. Our proposed algorithm reduces H/W complexity of polar decoder while preserving decoding performance.
