Equalization of Sparse Intersymbol-Interference Channels Revisited

open access: yesEURASIP Journal on Wireless Communications and Networking, 2006
Sparse intersymbol-interference (ISI) channels are encountered in a variety of communication systems, especially in high-data-rate systems. These channels have a large memory length, but only a small number of significant channel coefficients.

Multiple-Input-Multiple-Output Filtered Multitone Time Reversal Acoustic Communications Using Direct Adaptation-Based Turbo Equalization [PDF]

open access: yesSensors, 2023
This paper proposes using direct adaptation (DA)-based turbo equalization in multiple-input-multiple-output (MIMO) filtered multitone (FMT) time reversal (TR) acoustic communications to jointly suppress noise, residual co-channel interference (CCI) and ...

A Photolysis-Assist Molecular Communication for Tumor Biosensing [PDF]

open access: yesSensors, 2022
Molecular communication (MC) is a promising bioinspired paradigm for exchanging molecule information among nanomachines. In this paper, we propose a synchronization-assist photolysis MC system that aims to transmit the biosensing signal of the tumor ...

Chaotic Pulse-Shaping Filter Based on Root-Raised-Cosine Division [PDF]

open access: yesEntropy, 2023
Chaotic baseband wireless communication system (CBWCS) suffers bit error rate (BER) degradation due to their intrinsic intersymbol interference (ISI). To this end, an ISI-free chaotic filter based on root-raised-cosine (RRC) division is constructed to ...

The criterion for the existence of the weight of the orthogonality of equidistant elementary signals [PDF]

open access: yesITM Web of Conferences, 2019
To reduce the level of intersymbol interference and interchannel interference, it is proposed to form the transmitted signals using the basis functions obtained by shifting the impulse responses of linear systems by multiple time intervals.

Estimating Interference with a Two-Dimensional Viterbi Algorithm for Bit-Patterned Media Recording

open access: yesApplied Sciences, 2022
Bit-patterned media recording (BPMR) is proposed as a candidate for future magnetic data storage to overcome superparamagnetism. The distance between magnetic islands in BPMR must be reduced to increase the areal density (AD).

A Body Channel Communication Technique Utilizing Decision Feedback Equalization

open access: yesIEEE Access, 2020
This article presents the body channel communication technique that first adopts decision feedback equalisation. For the first time, we characterised post-cursor intersymbol interference of a single-bit pulse response of a human body channel for decision

Modulation Decoding Based on K-Means Algorithm for Bit-Patterned Media Recording

open access: yesApplied Sciences, 2022
In bit-patterned media recording (BPMR) systems, the readback signal is affected by neighboring islands that are characterized by intersymbol interference (ISI) and intertrack interference (ITI).

One-Dimensional Detection Using Interference Estimation by Multilayered Two-Dimensional General Partial Response Targets for Bit-Patterned Media Recording Systems

open access: yesApplied Sciences, 2022
In bit-patterned media recording (BPMR) systems, two-dimensional (2D) interference, which includes intersymbol and intertrack interference from down- and across-track directions, respectively, increases when the distance between the islands is reduced ...
