Web10 de jul. de 2024 · It was shown in that a properly designed pre-transformation such as convolutional transform can improve the distance properties of polar codes. Fig. 1: PAC Coding Scheme In [ 5 ] , we studied the implementation of tree search algorithms including the conventional list decoding and complexity-efficient Fano decoding for PAC 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 … WebReed Muller (RM) codes are known for their good minimum distance. One can use their structure to construct polar-like codes with good distance properties by choosing the information set as the rows of the polarization matrix with the highest Hamming weight, instead of the most reliable synthetic channels. However, the information length options … rcw growth management act
