Polar Codes With Repeating Bits and the Construction by Cluster Pairwise Error Probability [PDF]

open access: yesIEEE Access, 2019
A polar code with repeating bits (RB polar code), where a part of frozen bits only repeat their preceding information bits, is proposed. In the code construction, we propose cluster pairwise error probability (CPEP) to measure the competitiveness of the ...

A Framework for Characterization of Optimal Decision Rules in Hypothesis-Testing Problems [PDF]

open access: yesEntropy
In this review paper, we present a framework for the characterization of optimal decision rules in M-ary hypothesis-testing problems where the performance metric is defined as a function of pairwise error probabilities.

Joint Coherent/Non-Coherent Detection for Distributed Massive MIMO: Enabling Cooperation Under Mixed Channel State Information [PDF]

open access: yesSensors
Beyond-5G wireless systems increasingly rely on distributed massive multiple-input multiple-output (MIMO) architectures to achieve high spectral efficiency, low latency, and wide coverage.

Design and Performance Analysis of Probabilistically Shaped QAM Signals for Coherent FSO Systems with Gamma-Gamma Turbulence Channels

open access: yesApplied Sciences, 2021
Probabilistic shaping (PS) is a promising technique to approach the Shannon limit. In this paper, we design a practical coded modulation scheme based on PS to improve the capacity of coherent free-space optical (FSO) links with quadrature amplitude ...

Multi‐user uplink transmission with asymptotic full‐receiver‐diversity in massive MIMO systems

open access: yesIET Communications, 2021
A scenario of uplink transmissions from multiple single‐antenna users to a base‐station with large number of antennas is considered in this letter. Based on the conditional statistic properties of the received signals, a maximum likelihood‐based detector

SWIPT-Enabled Cooperative NOMA With mth Best Relay Selection

open access: yesIEEE Open Journal of the Communications Society, 2020
Non-orthogonal multiple access (NOMA) was recently regarded as a potential technique for next generation wireless networks. Recent works on relay selection for cooperative NOMA systems have mainly addressed the best relay selection to forward its ...

Cooperative DF Protocol for MIMO Systems Using One-Bit ADCs

open access: yesSensors, 2022
This study considers a detection scheme for cooperative multi-input–multi-output (MIMO) systems using one-bit analog-to-digital converters (ADCs) in a decode-and-forward (DF) relay protocol.

Approximating the pairwise error probability forfading channels

open access: yesElectronics Letters, 1995
The computation of the pairwise error probability (PEP) for coded digital communications in the presence of fading is often performed by using the Chernoff upper bound, which is simple to evaluate but rather loose. Exact evaluation of the PEP is possible in principle by computing the residues of a complex function, but this may be complicated in ...

Exact pairwise error probability analysis of space-time codes in spatially correlated fading channels

open access: yesJournal of Telecommunications and Information Technology, 2006
In this paper, we derive an analytical expression for the exact pairwise error probability (PEP) of a space-time coded system operating over a spatially correlated slow fading channel using a moment-generating function-based approach.
