In this paper, we propose robust power allocation and admission control schemes for
providing probabilistically constrained quality of service (QoS) in selective relaying based …

In this paper, we study resource allocation and relay selection in a decode-and-forward
downlink OFDMA cooperative network assuming imperfect channel state information (CSI) …

Cooperative communications can achieve spatial diversity gain and enhance coverage.
However, conventional half-duplex relaying schemes suffer from the loss in spectral …

This paper presents a comprehensive performance analysis of multiuser multiple antenna
amplify-and-forward relaying networks employing opportunistic scheduling with feedback …

In this paper, we consider a coded cooperation diversity scheme that is suitable for L-relay
channels that operate in the decode-forward mode. The proposed scheme is based on …

In this letter, we investigate the impact of receive diversity on the error rate performance of a
relay-assisted cooperative scheme in which the relay terminal is operating in amplify-and …

We deal with the concept of physical-layer fairness in amplify and forward cooperative
diversity systems, which reflects the need for equally allocating the consumed power among …

Relays are used in the current wireless standards to enhance the cell throughput and
coverage. In this paper, we evaluate the system performance by considering the duplexing …

We consider a dense fading multi-user network with multiple active multi-antenna source-
destination pair terminals communicating simultaneously through a large common set of K …

Space, cost, and signal processing constraints, among others, often preclude the use of
multiple antennas at wireless terminals. This paper investigates distributed decode-and …
