Performance evaluation of hybrid ARQ schemes of 3GPP LTE OFDMA system [PDF]

open access: yes, 2007
Expectations and requirements for future wireless communication systems continue to grow and evolve. Thus, recently, the Third Generation Partnership Project (3GPP) has considered the Long Term Evolution (LTE) of 3G - also known as Super 3G - to ensure ...

A Reduced-Complexity Detector for OFDMA/SC-FDMA-aided Space-Time Shift Keying [PDF]

open access: yes, 2013
We propose a novel reduced-complexity detector for the orthogonal frequency division multiple access (OFDMA)/single-carrier frequency division multiple access (SC-FDMA)-aided space-time shift keying (STSK) architecture.

A game theoretic approach to distributed resource allocation for OFDMA-based relaying networks [PDF]

open access: yes, 2008
In this paper, algorithms on distributed resource (spectrum and power) sharing for relay stations are investigated for downlink transmissions in an OFDMA-based relay-aided cell. Both system capacity and user fairness are considered. By grouping the relay

Statistical analysis of OFDMA assignments

open access: yes2008 IEEE International Symposium on Wireless Communication Systems, 2008
In this paper we investigate statistical properties of IP optimal subcarrier assignments in the down-link of an OFDMA cell. Essentially, we show that such subcarrier assignments do have ?hidden? statistical properties which can be exploited to design an extremely simple assignment strategy.

Resource allocation techniques for OFDMA-based decode-and-forward relaying networks [PDF]

open access: yes, 2008
In this paper, we focus on the design of efficient resource allocation algorithms for a multihop cellular network, with orthogonal frequency division multiple access (OFDMA) as downlink transmission technique and utilizing decode-and- forward cooperation

MU-MIMO enabled uplink OFDMA MAC protocol in dense IEEE 802.11ax WLANs

open access: yesICT Express, 2020
IEEE 802.11ax supports orthogonal frequency division multiple access (OFDMA) for uplink (UL) transmissions where stations (STAs) access randomly chosen resource units (RUs) in a distributed manner.

A distributed algorithm for wireless resource allocation using coalitions and the Nash bargaining solution [PDF]

open access: yes, 2011
In this paper a distributed, low-complexity, fast and fair resource allocation algorithm for a multiuser, wireless LTE OFDMA channel is proposed. Based on the game theoretic concept of the Nash Bargaining Solution and by grouping users into coalitions of
