Error correction performance of finite‐length polar codes has been a major concern in the past decade. This Letter presents a method for improving the error correction performance of cyclic redundancy check (CRC)‐aided successive cancellation list decoding for polar codes of medium block‐lengths with high code rates. In the proposed decoding scheme, a one‐time repetition of least reliable bit‐channels along with partial protection of the message is employed to correct the error(s) when decoding fails. The results show an improvement of nearly 0.2 dB in error correction performance.
