On Performance Comparison of Multi-Antenna HD-NOMA, SCMA and PD-NOMA Schemes [PDF]

arXiv, 2020
In this paper, we study the uplink channel throughput performance of a proposed novel multiple-antenna hybrid-domain non-orthogonal multiple access (MA-HD-NOMA) scheme. This scheme combines the conventional sparse code multiple access (SCMA) and power-domain NOMA (PD-NOMA) schemes in order to increase the number of users served as compared to ...

INTERNATIONAL MIGRATION AND TECHNOLOGICAL MANAGEMENT IN COFFEE PRODUCTION IN TWO COMMUNITIES IN THE CENTRAL AREA OF VERACRUZ STATE

Tropical and Subtropical Agroecosystems, 2011
Veracruz comes third in terms of national coffee production; however this sector is facing a crisis because of the fall in prices in the international market which has resulted amongst other things in increased emigration to the United States. The aim of

A Fair Individual Rate Comparison between MIMO-NOMA and MIMO-OMA

, 2017
In this paper, we compare the individual rate of MIMO-NOMA and MIMO-OMA when users are paired into clusters. A power allocation (PA) strategy is proposed, which ensures that MIMO-NOMA achieves a higher individual rate for each user than MIMO-OMA with ...

Acute freshwater CO2 exposure does not impair seawater transfer in three different sizes of Atlantic salmon (Salmo salar) subjected to different photoperiod manipulations

Journal of Fish Biology, EarlyView.
Abstract There is a growing interest in Atlantic salmon (Salmo salar) aquaculture to extend the time fish are reared in freshwater (FW) recirculating aquaculture systems (RAS), producing larger FW salmon that can then be induced to undergo smoltification before transfer into marine net pens for grow‐out and harvest.

A Systematic Literature Review on Auction Mechanisms: Insights From the Last Decade and Future Directions

Journal of Economic Surveys, EarlyView.
ABSTRACT This study reports the results of a systematic literature review on auctions mechanism. Auctions are a very popular practice employed in many fields but does not exist a research that investigates the use of auctions under a cross‐disciplinary approach. This work is focused on analyzing which are the areas where auctions are mostly adopted and

Performance Enhancement of Downlink NOMA by Combination with GSSK [PDF]

arXiv, 2018
In non-orthogonal multiple access (NOMA), cell-edge users experience significantly low spectral density because only some part of the total transmit power is allocated. This leads to low spectral efficiency for the paired users in NOMA. To overcome this problem, we propose an integration of NOMA and generalized space shift keying (GSSK), called NOMA ...
