WebThe coding scheme is based on concatenation of LDPC (Low-Density Parity-Check) and BCH codes. LDPC codes, invented by Gallager in his seminal doctoral thesis in 1960, can … WebAn end-to-end joint source–channel (JSC) encoding matrix and a JSC decoding scheme using the proposed bit flipping check (BFC) algorithm and controversial variable node selection-based adaptive belief propagation (CVNS-ABP) decoding algorithm are presented to improve the efficiency and reliability of the joint source–channel …

WebThe two-level parity-sharing scheme requires systematic en-coding of the information block. Columnwise decoding of the parity-sharing code (STEP 2, Fig. 2) assumes that parities of the row code are the information words of the column code. Without systematic column encoding, the row parities would be mapped to some other symbols during column ... emacs nethack
