On the undetected error probability of a concatenated coding scheme for error control [PDF]
Consider a concatenated coding scheme for error control on a binary symmetric channel, called the inner channel. The bit error rate (BER) of the channel is correspondingly called the inner BER, and is denoted by Epsilon (sub i). Two linear block codes, C(

PAPR Reduction Performance by Active Constellation Extension for Diversity MIMO-OFDM Systems
Journal of Electrical and Computer Engineering, 2010 The V-BLAST wireless communication architecture, space-time block code (STBC), and space-frequency block code (SFBC) techniques are strong candidates for achieving very high data rates in 4G broadband wireless communications.

New Lower Bounds for Permutation Codes using Linear Block Codes [PDF]
arXiv, 2019 In this paper we prove new lower bounds for the maximal size of permutation codes by connecting the theory of permutation codes with the theory of linear block codes. More specifically, using the columns of a parity check matrix of an $[n,k,d]_q$ linear block code, we are able to prove the existence of a permutation code in the symmetric group of ...

On the Decoding Performance of Spatially Coupled LDPC Codes with Sub-block Access [PDF]
arXiv, 2020 We study spatially coupled LDPC codes that allow access to sub-blocks much smaller than the full code block. Sub-block access is realized by a semi-global decoder that decodes a chosen target sub-block by only accessing the target, plus a prescribed number of helper sub-blocks adjacent in the code chain.

High performance short-block binary regular LDPC codes
Alexandria Engineering Journal, 2018 LDPC code shows a good performance with long-block codes. However, certain channels are constrained to use short-block codes due to latency. Therefore, concatenated LDPC codes with iterative decoding is a good choice to get a good performance ...

Repairable Block Failure Resilient Codes [PDF]
arXiv, 2014 In large scale distributed storage systems (DSS) deployed in cloud computing, correlated failures resulting in simultaneous failure (or, unavailability) of blocks of nodes are common. In such scenarios, the stored data or a content of a failed node can only be reconstructed from the available live nodes belonging to available blocks.

Rateless Space Time Block Code for Massive MIMO Systems
International Journal of Antennas and Propagation, 2014 This paper presents a rateless space time block code (RSTBC) for massive MIMO systems. The paper illustrates the basis of rateless space time codes deployments in massive MIMO transmissions over wireless erasure channels.

Detecting Java Code Clones Based on Bytecode Sequence Alignment
IEEE Access, 2019 When the source code is copied and pasted or modified, there will be a lot of identical or similar code snippets in the software system, which are called code clones.

Local homeomorphisms that *-commute with the shift [PDF]
arXiv, 2010 Exel and Renault proved that a sliding block code on a one-sided shift space coming from a progressive block map is a local homeomorphism. We provide a counterexample showing that the converse does not hold. We use this example to generalize the notion of progressive to a property of block maps we call weakly progressive, and we prove that a sliding ...
