On Pre-transformed Polar Codes DeepAI

WebIn this work, we present sufficient conditions to increase the information length by at least one bit for some underlying RM codes and in order to obtain pre-transformed polar-like codes with the same minimum distance than lower rate codes.The proofs give a constructive method to choose the row triples to be merged together to increase the … Web13 de dez. de 2024 · On Pre-transformed Polar Codes. In this paper, we prove that any pre-transformation with an upper-triangular matrix (including cyclic redundancy check (CRC), … WebPolar codes are the first class of channel codes achieving the symmetric capacity of the binary-input discrete memoryless channels with efficient encoding and decoding algorithms. But the weight spectrum of Polar codes is relatively poor compared to RM codes, which degrades their ML performance. Pre-transformation with an upper-triangular matrix … small cuts of beets
