Green communication via Type-I ARQ: Finite block-length analysis [PDF]

, 2014
This paper studies the effect of optimal power allocation on the performance of communication systems utilizing automatic repeat request (ARQ). Considering Type-I ARQ, the problem is cast as the minimization of the outage probability subject to an ...

Power Allocation by PSO in MAC [PDF]

Proceedings of the 2015 International Conference on Advances in Mechanical Engineering and Industrial Informatics, 2015
The capacity of Additive White Gaussian Noise (AWGN) Multiple Access Channel (MAC) can be approached by means of power allocation. The MAC can be regarded as single user multiple level coding and modulation system by applying pulse amplitude modulation to the individual signal and superimposing the weighted signal.

A new NOMA approach for fair power allocation [PDF]

2016 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2016
A non-orthogonal multiple access (NOMA) approach to user signal power allocation called Fair-NOMA is introduced. Fair-NOMA is the application of NOMA in such a way that two mobile users have the opportunity to always achieve at least the information capacity they can achieve by using orthogonal multiple access (OMA), regardless of the user selection ...

Spatial and temporal evolution trends of groundwater drought and its correlation with meteorological drought in Guizhou province

Agricultural Water Management
Groundwater constitutes a vital water resource in karst regions, where conventional surface-based drought indicators frequently fail to accurately capture groundwater deficits. However, the applicability of GRACE satellite data for monitoring groundwater

Resource Allocation in Wireless Powered IoT Networks [PDF]

IEEE Internet of Things Journal, 2019
In this paper, efficient resource allocation for the uplink transmission of wireless powered IoT networks is investigated. We adopt LoRa technology as an example in the IoT network, but this work is still suitable for other communication technologies.

Photosynthesis under far‐red light—evolutionary adaptations and bioengineering of light‐harvesting complexes

FEBS Letters, EarlyView.
Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.

A bioinformatics screen identifies TCF19 as an aggressiveness‐sustaining gene in prostate cancer

Molecular Oncology, EarlyView.
Gene expression meta‐analysis in multiple prostate cancer patient cohorts identifies Transcription factor 19 (TCF19) as an aggressiveness‐sustaining gene with prognostic potential. TCF19 is a gene repressed by androgen signaling that sustains core cancer‐related processes such as vascular permeability or tumor growth and metastasis.

Optimal downlink power allocation in cellular networks [PDF]

Physical Communication, 2015
In this paper, we introduce a novel approach for power allocation in cellular networks. In our model, we use sigmoidal-like utility functions to represent different users' modulation schemes. Each utility function is a representation of the probability of successfully transmitted packets per unit of power consumed by a user, when using a certain ...
