Enhancement of the QoS in an OFDMA/VLC system
(INSTITUTE OF ELECTRICAL AND ELECTRONICS ENGINEERS INC., 2016-07-20)
A resource allocation optimization for indoor Optical Wireless Communications is proposed. A smart coordinator tries to maximize the channel capacity by enabling or disabling the communication of the devices subject to ...
Estimation Aveugle Itérative par Filtrage H∞ des Décalages Doppler d’un Système OFDMA Entrelacé en Liaison Montante
(2009-07-01)
Il s'agit d'estimer et de compenser de multiples décalages Doppler dans un contexte multi-(porteuses, utilisateurs) OFDMA en liaison montante. Pour cela, nous proposons une architecture de réception itérative capable ...
Resource Allocation for Joint Transmitter and Receiver Energy Efficiency Maximization in Downlink OFDMA Systems
(IEEE, 2015)
This paper investigates the joint transmitter and receiver
optimization for the energy efficiency (EE) in orthogonal
frequency-division multiple-access (OFDMA) systems. We first
establish a holistic power dissipation ...
Carrier Frequency Offset Compensation for OFDMA Systems Using Circular Banded Matrices
(Planta Piloto de Ingeniería Química, 2013-07)
Orthogonal frequency division multiple access (OFDMA) is a multiuser communication technique that allocates to each user a set of orthogonal carriers. In the presence of carrier frequency offset (CFO) the orthogonality ...
A low complexity algorithm for dynamic fair resource allocation in OFDMA systems
(Universidade Federal de Pernambuco, 2014)
Estudio de OFDMA en el enlace de bajada en LTE
(Serrano Leon Wendy Aline, Cortes Perez Rogelio Christian, Valdés Hernandez Samuel Moises, 2017-05-25)
En este trabajo se presenta la recreación a escala del símbolo OFDMA teniendo como base los parámetros establecidos por el estándar de LTE en el enlace descendente de su interfaz aérea. Para llevar a cabo este proceso se ...
Analysis of the CFO Successive Interference Cancellation for the OFDMA Uplink
(Springer, 2016-11)
The uplink of orthogonal frequency division multiple access or single-carrier frequency division multiple access suffers multiple access interference when carrier frequency offset (CFO) is not properly estimated and ...
