WebN2 - A new family of modified polar codes and a new permutation selection scheme for belief propagation list (BPL) decoding are presented. We first propose a new code … LDPC codes can be compared with other powerful coding schemes, e.g. turbo codes. In one hand, BER performance of turbo codes is influenced by low codes limitations. LDPC codes have no limitations of minimum distance, that indirectly means that LDPC codes may be more efficient on relatively large code rates (e.g. 3/4, 5/6, 7/8) than turbo codes. However, LDPC codes are not the complete replacement: turbo codes are the best solution at the lower code rates (e.g. 1/6, 1/… WebAbstract: In this paper, we propose a construction of parity-check equations for Low Density Parity-Check (LDPC) based Parity-Check Concatenated (PCC) polar codes in order to (i) increase the minimum Hamming weight and (ii) correct some errors using belief propagation decoding. We simulate some experiment to show that the proposed LDPC … gallions reach cinema
