Frequency-Domain Turbo Equalisation in Coded SC-FDMA Systems: EXIT Chart Analysis and Performance [PDF]

open access: yes, 2012
In this paper, we investigate the achievable performance of channel coded single-carrier frequency division multiple-access (SC-FDMA) systems employing various detection schemes, when communicating over frequency-selective fading channels.

Difficult-to-transport cases and neurological outcomes of out-of-hospital cardiac arrest: A population-based nationwide study in Japan. [PDF]

open access: yesAcute Med Surg
A higher proportion of difficult‐to‐transport cases was associated with poorer neurological outcomes and longer transport times in patients with OHCA. Abstract Aim In Japan, emergency medical service personnel often have difficulty obtaining hospitals' acceptance of emergency cases owing to congestion in the emergency unit; such cases are called ...

Area spectral efficiency of soft-decision space–time–frequency shift-keying-aided slow-frequency-hopping multiple access [PDF]

open access: yes, 2012
Slow-frequency-hopping multiple access (SFHMA) can provide inherent frequency diversity and beneficially randomize the effects of cochannel interference.

Design of SIMO SC-FDMA-DMWT transceiver using maximal-ratio combining in LoS fading channels [PDF]

open access: yesSerbian Journal of Electrical Engineering
In this paper single-input multiple-output (SIMO) transceivers employing single-carrier Frequency Division Multiple Access with Discrete Multi- Wavelet Transform (SC-FDMA-DMWT) for 3GPP Long Term Evolution (LTE) uplink channels are considered.

Admissibility via Natural Dualities [PDF]

open access: yes, 2015
It is shown that admissible clauses and quasi-identities of quasivarieties generated by a single finite algebra, or equivalently, the quasiequational and universal theories of their free algebras on countably infinitely many generators, may be ...

Non-orthogonal multiple-access system SC-FDMA-IDMA with iterative block equalization

open access: yesTongxin xuebao, 2014
As a new non-orthogonal multiple-access scheme, SC-FDMA-IDMA combines two technologies of SC-FDMA and IDMA together. This combination makes SC-FDMA-IDMA have the probability to inherit different advantages of these two technologies such as large system ...

Simplified approach for symbol error rate analysis of SC‐FDMA scheme over Rayleigh fading channel

open access: yesETRI Journal, 2018
In this paper, we present a comprehensive analytical study of the symbol error rate (SER) of single‐carrier frequency‐division multiple access (SC‐FDMA) with zero‐forcing frequency domain equalization (ZF‐FDE) over a Rayleigh fading channel.

Frequency-domain precoding for single carrier frequency-division multiple access [PDF]

open access: yes, 2009
At present there is considerable interest in the use of single carrier frequency-division multiple access. This interest is justified by the inherent single carrier structure of the SC-FDMA scheme, which is more robust against phase noise and has a lower

On the Information Rate of Single-Carrier FDMA Using Linear Frequency Domain Equalization and Its Application for 3GPP-LTE Uplink

open access: yesEURASIP Journal on Wireless Communications and Networking, 2009
This paper compares the information rate achieved by SC-FDMA (single-carrier frequency-division multiple access) and OFDMA (orthogonal frequency-division multiple access), where a linear frequency-domain equalizer is assumed to combat frequency selective

Large-Scale MIMO Detection for 3GPP LTE: Algorithms and FPGA Implementations [PDF]

open access: yes, 2014
Large-scale (or massive) multiple-input multiple-output (MIMO) is expected to be one of the key technologies in next-generation multi-user cellular systems, based on the upcoming 3GPP LTE Release 12 standard, for example.
