SGD Frequency-Domain Space-Frequency Semiblind Multiuser Receiver with an Adaptive Optimal Mixing Parameter [PDF]
, 2013 A novel stochastic gradient descent frequency-domain (FD) space-frequency (SF) semiblind multiuser receiver with an adaptive optimal mixing parameter is proposed to improve performance of FD semiblind multiuser receivers with a fixed mixing parameters ...

Journal of Fish Diseases, EarlyView.ABSTRACT Flavobacterium spp. are the etiological agents of columnaris disease. Although there is evidence that columnaris poses a significant threat to the farming of tambaqui (Colossoma macropomum), there remains a large gap in understanding the genetic and phenotypic diversities of columnaris‐causing bacteria (CCB).

Low complexity uplink multiuser MIMO detecting algorithm
Tongxin xuebao, 2010 Aiming at the uplink multiuser MIMO system,a new space-time detecting algorithm was proposed,in which a linear recombination strategy was imposed on the received signal first,and then the matched filter vectors orthogonal to each users’ interference sets

Comparative Analysis of the Tumour Mutational Burden in Erosive and Reticular Oral Lichen Planus
Oral Diseases, EarlyView.ABSTRACT Objective Oral lichen planus (OLP) is a chronic inflammatory disease classified as an oral potentially malignant lesion. The erosive and reticular forms of OLP have the potential for malignant transformation, with no consistent data indicating that one form is more likely to undergo malignant transformation than the other.

Randomly Spread CDMA: Asymptotics via Statistical Physics
, 2005 This paper studies randomly spread code-division multiple access (CDMA) and multiuser detection in the large-system limit using the replica method developed in statistical physics. Arbitrary input distributions and flat fading are considered.

Beam Training and Allocation for Multiuser Millimeter Wave Massive MIMO Systems [PDF]
IEEE Transactions on Wireless Communications, 2019 We investigate beam training and allocation for multiuser millimeter wave massive MIMO systems. An orthogonal pilot-based beam training scheme is first developed to reduce the number of training times, where all users can simultaneously perform the beam ...

Rational Feelings for Virtual Things?
Philosophical Issues, EarlyView.ABSTRACT This article examines the rationality of affective responses to virtual phenomena. I argue that at least some such responses can be perfectly rational, but that virtual realism and virtual irrealism—competing views about the metaphysics of the virtual—differ in their verdicts about the possible rationality of certain types of responses ...

Low Complexity Wireless Powered Information Transfer Strategy for Multiuser MIMO Systems
IEEE Access, 2018 In this paper, the minimum achievable rate maximization problem for wireless-powered multiple users is investigated. Zero-forcing (ZF)-based precoding is considered for information transmission (IT) in the uplink from multi-antenna users to a multi ...
