On pre-transformed polar codes
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 … WebN and uAc = 0, the codeword of the pre-transformed polar codes is given by xN 1 =uN 1 G N =u N 1 TF N. In original polar codes, the frozen bits are fixed to be zeros. While in …
