General signal model for orthogonal-frequency-division multiple access cellular networks with multiple amplify-and-forward relays has been introduced. An optimization problem mini...
Abstract-- Relaying and orthogonal frequency division multiple access (OFDMA) are the accepted technologies for emerging wireless communications standards. The activities in many w...
Abstract—This study considers an orthogonal frequencydivision multiple-access (OFDMA)-based multi-user two-way relay network where multiple mobile stations (MSs) communicate with...
Abstract— Cooperative relay networks combined with Orthogonal Frequency Division Multiplexing Access (OFDMA) technology has been widely recognized as a promising candidate for fu...
Abstract—This paper investigates Orthogonal FrequencyDivision Multiple-Access (OFDMA) resource-allocation schemes for two-hop relays in a home Powerline Communication (PLC) netwo...
