Iterative channel equalization, channel decoding and source decoding [PDF]
2005 IEEE 61st Vehicular Technology Conference, 2005 The performance of soft source decoding is evaluated over dispersive AWGN channels. By employing source codes having error-correcting capabilities, such as Reversible Variable-Length Codes (RVLCs) and Variable-Length Error-Correcting (VLEC) codes, the ...

Shuffled Iterative Decoding [PDF]
IEEE Transactions on Communications, 2005 Shuffled versions of iterative decoding of low-density parity-check codes and turbo codes are presented. The proposed schemes have about the same computational complexity as the standard versions, and converge faster. Simulations show that the new schedules offer better performance/complexity tradeoffs, especially when the maximum number of iterations ...

An Efficient Two-Stage Decoding Scheme for LDPC-CRC Concatenated Codes [PDF]
EntropyIn modern communication systems, the concatenation of a low-density parity-check (LDPC) code with a cyclic redundancy check (CRC) code is commonly used for error correction.

Iterative Reed-Muller Decoding [PDF]
2021 11th International Symposium on Topics in Coding (ISTC), 2021 Reed-Muller (RM) codes are known for their good maximum likelihood (ML) performance in the short block-length regime. Despite being one of the oldest classes of channel codes, finding a low complexity soft-input decoding scheme is still an open problem. In this work, we present a belief propagation (BP) decoding architecture for RM codes based on their

Symbol-level iterative information set decoding of RS codes
Alexandria Engineering Journal, 2023 This paper presents the implementation of a low-complex iterative symbol-level decoding scheme for Reed-Solomon codes. Most soft-decision iterative decoders for Reed-Solomon codes work on a bit level due to the efficient passing of soft information due ...

IEEE Information Theory Workshop, 2005., 2005 We analyze the relation between iterative decoding and the properties of the extended parity check matrix. By considering a modified version of bit flipping, which produces a list of decoded words, we derive several relations between decodable error patterns and parameters of the code.

Stochastic iterative decoders [PDF]
Proceedings. International Symposium on Information Theory, 2005. ISIT 2005., 2005 This paper presents a stochastic algorithm for iterative error control decoding. We show that the stochastic decoding algorithm is an approximation of the sum-product algorithm. When the code's factor graph is a tree, as with trellises, the algorithm approaches maximum a-posteriori decoding.

Optimum non-iterative turbo-decoding [PDF]
Proceedings of 8th International Symposium on Personal, Indoor and Mobile Radio Communications - PIMRC '97, 2002 By observing the structure of the decoder's trellis a new, non-iterative turbo-decoder based on a super-trellis structure is proposed, which exhibits the same decoding complexity as a conventional convolutional decoder possessing an identical number of trellis states.
