” Protograph LDPC Codes with Block Thresholds: Extension to Degree-1″.

September 21, 2017 @ 2:00 pm - 3:00 pm


Speaker : Asit Kumar Pradhan (EE13D021)

Protograph low-density-partiy-check (LDPC) are considered to design near-capacity low – rate codes over the binary erasure channel (BEC) and binary additive white Gaussian noise (BIAWGN) channel. For protographs with degree-one variable nodes and doubly-generalized LDPC (DGLDPC) codes a condition is derived to ensure equality of bit-error threshold and block-error threshold for both BEC and BIAWGN channel. Using this condition, low-rate codes with block – error threshold close to capacity are designed and shown to have better error rate performance than other existing codes.
