Techniques for providing greater error protection to error-prone bits in codewords generated from irregular codes
Greater error protection is provided to error-prone bits that are generated from irregular soft-decoded error correction codes. Error protection is increased to error-prone bits that of interest in a particular system (e.g., parity check bits). One or more extra bits are added to each codeword in the encoding process. The one or more extra bits correspond to lower weights. The one or more extra bits are discarded after each codeword is decoded.
