A Janus compatible software-defined underwater acoustic multiple-input multiple-output modem
International Journal of Distributed Sensor Networks, 2021 This article describes the implementation of a multiple-input multiple-output acoustic communication link in shallow water conditions to enable a software-defined acoustic modem with a maximum transmission rate of 20 kbps in a 5-kHz bandwidth.

Quasi-Cyclic Asymptotically Regular LDPC Codes
, 2010 Families of "asymptotically regular" LDPC block code ensembles can be formed by terminating (J,K)-regular protograph-based LDPC convolutional codes. By varying the termination length, we obtain a large selection of LDPC block code ensembles with varying ...

Codewords generated by UP-valued functions
AIMS Mathematics, 2021 The concept of a UP-valued function on a nonempty set was introduced by Ansari et al. [3]. Codewords in a binary block-code generated by a UP-valued function are established and some interesting results are obtained.

Integer sequences that are generalized weights of a linear code [PDF]
arXiv, 2023 Which integer sequences are sequences of generalized weights of a linear code? In this paper, we answer this question for linear block codes, rank-metric codes, and more generally for sum-rank metric codes. We do so under an existence assumption for MDS and MSRD codes.

Block Codes on Pomset Metric [PDF]
arXiv, 2022 Given a regular multiset $M$ on $[n]=\{1,2,\ldots,n\}$, a partial order $R$ on $M$, and a label map $\pi : [n] \rightarrow \mathbb{N}$ defined by $\pi(i) = k_i$ with $\sum_{i=1}^{n}\pi (i) = N$, we define a pomset block metric $d_{(Pm,\pi)}$ on the direct sum $ \mathbb{Z}_{m}^{k_1} \oplus \mathbb{Z}_{m}^{k_2} \oplus \ldots \oplus \mathbb{Z}_{m}^{k_n ...

Codes with Weighted Poset Block Metrics [PDF]
arXiv, 2023 Weighted poset block metric is a generalization of weighted poset metric introduced by Panek et al. ([\ref{panek}]) and the metric for linear error-block codes introduced by Feng et al. ([\ref{FENG}]). This type of metrics includes many classical metrics such as Hamming metric, Lee metric, poset metric, pomset metric, poset block metric, pomset block ...

Full-diversity design criterion for multi-user STBC based on integer-forcing detection
Tongxin xuebao, 2019 Multi-user space time block code systems have the problem of high decoding complexity.To ensure good system performance with low decoding complexity at the same time,low complexity integer-forcing (IF) detection algorithm was applied to multi-user space ...

Journal of Engineering and Sustainable Development, 2011 All coding algorithms including the linear block code provides explicit ways of ensuring that message remains legible even in the presence of errors, but without security. So a modified method to the linear block code that provides both error free and
