Wireless Communications and Mobile Computing, Volume 2017, Issue 1, 2017., 2017 This paper addresses the performance analysis of an adaptive wireless link with one antenna transmitter and a multiple antenna maximum‐ratio combining (MRC) receiver. Two main assumptions are used in this paper: (1) Rayleigh fading correlated channels (i.e., MRC branch correlation) and (2) imperfect (outdated) channel state information at the ...

A Novel Biobjective Risk‐Based Model for Stochastic Air Traffic Network Flow Optimization Problem
The Scientific World Journal, Volume 2015, Issue 1, 2015., 2015 Network‐wide air traffic flow management (ATFM) is an effective way to alleviate demand‐capacity imbalances globally and thereafter reduce airspace congestion and flight delays. The conventional ATFM models assume the capacities of airports or airspace sectors are all predetermined.

An outer bound on the MIMO BC with evolving current CSIT and perfect delayed CSIT
2014 6th International Symposium on Communications, Control and Signal Processing (ISCCSP), 2014 We derive a DoF outer bound for the two-user multiple-input multiple-output broadcast channel (MIMO BC) with good-quality delayed channel state information at the transmitter (perfect quality delayed CSIT), and with current CSIT of evolving quality (evolving current CSIT).

Retrospective Interference Alignment for Two-Cell Uplink MIMO Cellular Networks with Delayed CSIT
, 2015 In this paper, we propose a new retrospective interference alignment for two-cell multiple-input multiple-output (MIMO) interfering multiple access channels (IMAC) with the delayed channel state information at the transmitters (CSIT).

Precoding Method Interference Management for Quasi‐EVD Channel
The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014 The Cholesky decomposition‐block diagonalization (CD‐BD) interference alignment (IA) for a multiuser multiple input multiple output (MU‐MIMO) relay system is proposed, which designs precoders for the multiple access channel (MAC) by employing the singular value decomposition (SVD) as well as the mean square error (MSE) detector for the broadcast ...

RETRACTED: Resource allocation for integrated satellite‐terrestrial networks based on RSMA
IET Communications, Volume 19, Issue 1, January/December 2025.We first establish a downlink transmission framework for the integrated satellite‐terrestrial network based on RSMA, to achieve high data rate transmission of virtual reality applications globally. Then, considering some practical constraints, a joint resource allocation problem of rate and transmission power is formulated.

The Scientific World Journal, Volume 2014, Issue 1, 2014., 2014 We present in this work a low‐complexity algorithm to solve the sum rate maximization problem in multiuser MIMO broadcast channels with downlink beamforming. Our approach decouples the user selection problem from the resource allocation problem and its main goal is to create a set of quasiorthogonal users.

Smell loss is associated with cognitive impairment in amyotrophic lateral sclerosis patients
CNS Neuroscience &Therapeutics, Volume 30, Issue 7, July 2024.The olfactory performance of ALS patients is correlated with cognitive impairment, particularly frontotemporal dysfunction. Abstract Background Smell loss significantly impacts the quality of life in patients. However, there is limited research on smell loss in individuals with amyotrophic lateral sclerosis (ALS), and the correlation between smell loss

International Journal of Antennas and Propagation, Volume 2012, Issue 1, 2012., 2012 Although antenna selection is a simple and efficient technique for enhancing the downlink performance of multiuser diversity systems, the large antenna interelement spacing required for achieving spatial diversity is prohibitive for user terminals due to size restrictions.

Optimal DoF Region of the Two-User MISO-BC with General Alternating CSIT
, 2013 In the setting of the time-selective two-user multiple-input single-output (MISO) broadcast channel (BC), recent work by Tandon et al. considered the case where - in the presence of error-free delayed channel state information at the transmitter (delayed
