A novel method for encoding and decoding based on enhanced parity-check-concatenated polar codes
Dianxin kexue, 2021 Polar codes have perfect coding and decoding performance as a kind of error correction code, which have become a standard coding scheme for 5G short code control channel. While the length of polar codes is short, its performance is not good enough.

Long Nonbinary Codes Exceeding the Gilbert - Varshamov Bound for any Fixed Distance [PDF]
, 2004 Let A(q,n,d) denote the maximum size of a q-ary code of length n and distance d. We study the minimum asymptotic redundancy \rho(q,n,d)=n-log_q A(q,n,d) as n grows while q and d are fixed.

Area efficient parallel lfsr for cyclic redundancy check
International Journal of Electrical and Computer Engineering (IJECE), 2020 Cyclic Redundancy Check (CRC), code for error detection finds many applications in the field of digital communication, data storage, control system and data compression. CRC encoding operation is carried out by using a Linear Feedback Shift Register (LFSR).

Permutation Decoding and the Stopping Redundancy Hierarchy of Cyclic and Extended Cyclic Codes
, 2008 We introduce the notion of the stopping redundancy hierarchy of a linear block code as a measure of the trade-off between performance and complexity of iterative decoding for the binary erasure channel.

EVENODD: An Efficient Scheme for Tolerating Double Disk Failures in RAID Architectures [PDF]
, 1995 We present a novel method, that we call EVENODD, for tolerating up to two disk failures in RAID architectures. EVENODD employs the addition of only two redundant disks and consists of simple exclusive-OR computations.
