Hamming and Symbol-Pair Distances of Constacyclic Codes of Length 2ps over Fpm[u,v]⟨u2,v2,uv−vu⟩

open access: yesSymmetry
Let R=Fpm[u,v]⟨u2,v2,uv−vu⟩, where p is an odd prime and m is a positive integer. For a unit α in R, α-constacyclic codes of length 2ps over R are ideals of R[x]⟨x2ps−α⟩, where s is a positive integer. The structure of α-constacyclic codes are classified on the distinct cases for the unit α: when α is a square in R and when it is not.

A new class of MDS symbol-pair codes [PDF]

open access: yes, 2022
The symbol-pair code is a new coding framework proposed to guard against pair-errors in symbol-pair read channels. Especially, a symbol-pair code with the parameters achieving the Singleton-type bound is called an MDS symbol-pair code.

Linear Constellation Precoded OFDM With Interleaved Subcarrier Index Modulation

open access: yesIEEE Access, 2019
Orthogonal frequency-division multiplexing with index modulation (OFDM-IM) is an emerging and promising multicarrier transmission technique; however, frequency diversity achievement requires further investigation for the OFDM-IM.

A Family of Almost MDS Symbol-Pair Codes of Length 8p

open access: yesIEEE Access
In high-density data storage systems, symbol-pair codes are commonly used to prevent symbol-pair errors. Designing maximum distance separable (MDS) codes is crucial in symbol-pair coding theory because MDS symbol-pair codes are the best at meeting the ...

New families of MDS symbol-pair codes from matrix-product codes

open access: yes, 2023
In emerging storage technologies, the outputs of the channels consist of overlapping pairs of symbols. The errors are no longer individual symbols. Controlling them calls for a different approach. Symbol-pair codes have been proposed as a solution.

AMDS Symbol-Pair Codes from Repeated-Root Cyclic Codes

open access: yes, 2022
Symbol-pair codes are proposed to guard against pair-errors in symbol-pair read channels. The minimum symbol-pair distance is of significance in determining the error-correcting capability of a symbol-pair code.

MDS Symbol-Pair Codes from Repeated-Root Cyclic Codes

open access: yes, 2020
Symbol-pair codes are proposed to combat pair-errors in symbol-pair read channels. The minimum symbol-pair distance is of significance in determining the error-correcting capability of a symbol-pair code.

Two Classes of Reducible Cyclic Codes With Large Minimum Symbol-Pair Distances

open access: yesIEEE Transactions on Information Theory
The high-density data storage technology aims to design high-capacity storage at a relatively low cost. In order to achieve this goal, symbol-pair codes were proposed by Cassuto and Blaum \cite{CB10,CB11} to handle channels that output pairs of overlapping symbols.

Pharmacological chromatin remodeling enhances response to estrogen therapy in ER+ breast cancer

open access: yesMolecular Oncology, EarlyView.
Estrogen therapy elicits clinical benefit in ~ 30% of patients with endocrine‐resistant estrogen receptor (ER)‐positive breast cancer. Based on findings that ER transcriptional activation underlies response to estrogen therapy, we tested the effects of epigenetic dysregulation via pharmacological inhibition of histone deacetylases (HDACi).

OPTIMIZATION OF SYMBOL DISTANCE METRIC IN DIRECTIONAL MODULATION SYSTEMS

open access: yes, 2016
This paper investigates a directional modulation (DM) method that distorts the received symbol constellations along a set of undesired directions while maintaining an undistorted constellation in the direction of intended communications.
