The residual belief propagation (RBP) algorithm, which is the most classic informed dynamic scheduling strategy, achieves outstanding performance in error correction and can drastically accelerate convergence speed. However, the greedy algorithmic ...

According to the construction characteristics of base graph of protograph‐LDPC codes, informed dynamic scheduling (IDS) strategies are applied to an edge bundle of base matrices for the first time. The edge message with the maximum residual in each bundle ...

Scene text recognition has been widely investigated in computer vision. In the literature, the encoder-decoder based framework, which first encodes image into feature map and then decodes them into corresponding text sequences, have achieved great ...

We consider leveraging the joint potential of non‐orthogonal multiple access (NOMA) and traffic offloading to benefit cell‐edge users in multi‐cell scenarios. We formulate the edge‐driven throughput maximisation problem where both the offloading ...

Due to the time‐varyingproperty of the underwater acoustic (UWA) channel, the significant Doppler spread will severely degrade the performance of direct‐sequence spread‐spectrum (DSSS) communications. The relative velocity variation between the ...

Belief propagation (BP) is a soft‐decision (SD) decoder that is commonly used to obtain near‐optimal decoding performance for linear codes defined over sparse parity‐check matrix. Nevertheless, the BP yields poor performance when used in the decoding of ...

Frequency‐hopped M‐ary frequency‐shift‐keyed (FH‐MFSK) has the ability to handle with long multipath, large Doppler spreads, high ambient noise and rapid phase fluctuation, and is proved to be a robust modulation scheme in mobile shallow underwater ...

The protograph low‐density parity‐check (LDPC) codes possess many attractive properties, such as the low encoding/decoding complexity and better error floor performance, and hence have been successfully applied to different types of communication and ...

Fountain codes are promising forward error correction codes suitable for broadcast and multicast applications where many users with different capabilities are involved in the system. Fixed‐rate codes need a priori information about each channel to decide ...

Traditionally, concatenation of codes is used to increase the coding gain at the expense of the code rate and the throughput. In contrast, throughput enhancing concatenated codes (TECCs) are constructed here aiming to increase the throughput. In a TECC, ...

In this study, an irregular low‐density parity‐check (iLDPC) coded rate compatible modulation (iLDPC‐RCM) is proposed. A particularly designed interleaver is inserted between LDPC and RCM such that a fast convergence and a low bit‐error rate (BER) can be ...

The Luby transform (LT) code is the first practical implementation of the digital fountain code, and its utilisation over a noisy channel invokes iterative decoding with soft information. For a good decoding performance, the role of the encoder degree ...

In this work, the authors assess the performance and latency of a receiver design for multiuser multiple‐antenna systems using low‐density parity‐check (LDPC) codes with iterative detection and decoding (IDD). The proposed knowledge‐aided IDD (KA‐IDD) ...

Unequal error protection (UEP) divides the data into different levels of importance in order to ensure that the most important parts of the source information have more protection than the less important parts. In this study, the authors investigate the ...

Very large multi- input multi- output or massive MiMo (m-MiMo) is a promising approach to enhance energy efficiency for next generation wireless network 5G. However, m-MiMo suffers from pilot contamination which limits its performance. To resolve ...

In this study, a joint detection and generalised sum‐product decoding algorithm for a two‐way relay physical‐layer network coding (PLNC) system in power line communication is proposed. Distinct from the existing works which mainly focused on separate or ...

A new decoding strategy of belief propagation (BP) for low‐density parity‐check codes is presented by serially concatenating the traditional simultaneous decoding (also known as flooding) and the informed dynamic decoding (IDD) (e.g. node‐wise residual ...

The iterative header recovery algorithm holds the potential of improving the performance of wireless communication, yet it has to face the challenge of reducing the high complexity. In this study, a method of constructing a candidate set around the ...

Minimum mean square error (MMSE)‐based techniques are often used for the joint iterative detection and decoding that is for coded multi‐input–multi‐output (MIMO) system due to a sound complexity and the performance trade‐off. This study proposes an ...

A K‐user multi‐rate code is proposed for a Gaussian multiple access channel with binary inputs, equal‐power, and symbol synchronisation. In this multi‐rate transmission, K users are equally divided into M groups. For each user in the mth group, a rate‐1/...
