A Parity-Consistent Decomposition Method for the Weight Distribution of Pre-Transformed Polar Codes
Yang Liu, Bolin Wu, Yuxin Han +1
This paper introduces an efficient algorithm based on the Parity-Consistent Decomposition (PCD) method to determine the WD of pre-transformed polar codes. First, to address the bit…
