On Maximum Contention-Free Interleavers and Permutation Polynomials over Integer Rings [PDF]
, 2005 An interleaver is a critical component for the channel coding performance of turbo codes. Algebraic constructions are of particular interest because they admit analytical designs and simple, practical hardware implementation. Contention-free interleavers

Hardware Design of Concatenated Zigzag Hadamard Encoder/Decoder System With High Throughput
IEEE Access, 2020 Both turbo Hadamard codes and concatenated zigzag Hadamard codes are ultimate-Shannonlimit-approaching channel codes. The former one requires the use of Bahl-Cocke-Jelinek-Raviv (BCJR) in the iterative decoding process, making the decoder structure more ...

Multi-level Turbo Decoding Assisted Soft Combining Aided Hybrid ARQ [PDF]
, 2010 Hybrid Automatic Repeat reQuest (ARQ) plays an essential role in error control. Combining the incorrectly received packet replicas in hybrid ARQ has been shown to reduce the resultant error probability, while improving the achievable throughput.

Exit chart analysis of parallel data convolutional codes [PDF]
, 2005 We recently proposed a new class of turbo-like codes called parallel data convolutional codes (PDCCs). The distinct characteristics of PDCCs include parallel data input bits and a self-iterative soft-in/soft-out a posteriori probability(APP) decoder. In

Semi-Iterative Analog Turbo Decoding [PDF]
IEEE Transactions on Circuits and Systems I: Regular Papers, 2007 Based on multiple-slice turbo codes, a novel semi-iterative analog turbo decoding algorithm and its corresponding decoder architecture are presented. This work paves the way for integrating flexible analog decoders dealing with frame lengths over thousands of bits.
