Researchers in both academia and industry have accepted OFDMA as the most appropriate
air-interface for the emerging broadband wireless access networks and standards. A …

The opportunities and flexibility in relay networks and orthogonal frequency-division multiple
access (OFDMA) make the combination a suitable candidate network and air-interface …

In this paper, we formulate a joint optimization problem for resource allocation and
scheduling in full-duplex multiple-input multiple-output orthogonal frequency division …

In this paper, a point-to-point orthogonal-frequency-division multiplexing (OFDM) system
with a decode-and-forward (DF) relay is considered. The transmission consists of two hops …

In this paper, we formulate resource allocation and scheduling for multi-cell orthogonal
frequency division multiple access (OFDMA) systems with half-duplex decode-and-forward …

Relaying and orthogonal frequency division multiple access (OFDMA) are the accepted
technologies for emerging wireless communications standards. The activities in many …

Wireless communications have gained huge attention over the past decades because of
continuously increasing demands. The main goal of all wireless network designers is to …

A two-way relay channel (TWRC) in which two terminals T 1 and T 2 exchange orthogonal
frequency division multiplexing (OFDM) signals with the help of an amplify-and-forward (AF) …

In relay-aided wireless transmission systems, one of the key issues is how to manage the
energy resource at the source and each individual relay, to optimize a certain performance …

In this paper, a low-complexity delay-aware cross-layer scheduling algorithm for two-hop
relay communication systems is proposed. The complex interactions of the queues at the …
