Iterative Detection and Decoding Algorithms for MIMO Systems in Block-Fading Channels Using LDPC Codes [PDF]
IEEE Transactions on Vehicular Technology, 2015 We propose iterative detection and decoding (IDD) algorithms with low-density parity-check (LDPC) codes for multiple-input multiple-output (MIMO) systems operating in block-fading and fast Rayleigh fading channels.

A Hypergraph Filtering Based Iterative Decoding Approach for Linear Channel Codes
IEEE Access, 2021 Efficient decoding for general linear channel codes has been a long standing problem. Message passing type algorithms can achieve near-optimal performance for channel codes with sparse check matrices and long code-lengths, but they may suffer from ...

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.

Iterative detection and decoding for SCMA systems with LDPC codes [PDF]
International Conference on Wireless Communications and Signal Processing, 2015 Sparse code multiple access (SCMA) is a promising multiplexing approach to achieve high system capacity. In this paper, we develop a novel iterative detection and decoding scheme for SCMA systems combined with Low-density Parity-check (LDPC) decoding. In

Deterministic Non-Autoregressive Neural Sequence Modeling by Iterative Refinement [PDF]
Conference on Empirical Methods in Natural Language Processing, 2018 We propose a conditional non-autoregressive neural sequence model based on iterative refinement. The proposed model is designed based on the principles of latent variable models and denoising autoencoders, and is generally applicable to any sequence ...

Iterative Pseudo-Labeling for Speech Recognition [PDF]
Interspeech, 2020 Pseudo-labeling has recently shown promise in end-to-end automatic speech recognition (ASR). We study Iterative Pseudo-Labeling (IPL), a semi-supervised algorithm which efficiently performs multiple iterations of pseudo-labeling on unlabeled data as 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 ...

Iterative decoding of Gold sequences [PDF]
2015 IEEE International Conference on Communications (ICC), 2015 Gold sequences are widely used in communications and positioning systems for synchronization purposes or spread spectrum transmissions. This paper addresses the decoding of the initial state of a Gold sequence. This can be used to detect a harmful interferer closed to a 3G femtocell base station and implement interference mitigation techniques.
