In this correspondence, we advocate the exploitation of direct links for downlink cooperative
cellular networks, where one base station (source) communicates with one out of N mobile …

In this paper, the performance of cellular networks with joint multicell processing and
dedicated relay terminals is investigated. It is assumed that each relay terminal is capable of …

User cooperation, whereby multiple users share their antennas and transmit to a common
destination in a collaborative manner, has been shown to be an effective way to achieve …

We consider relay selection technique in a cooperative cellular network where user
terminals act as mobile relays to help the communications between base station (BS) and …

Energy-efficient communication is an important requirement for mobile relay networks due to
the limited battery power of user terminals. This paper considers energy-efficient relaying …

Capacity gains from transmitter and receiver cooperation are compared in a relay network
where the cooperating nodes are close together. Under quasi-static phase fading, when all …

In this paper, we investigate a relay enhanced cellular system, where a relay station is
located in the overlap area served by two base stations. We propose cooperative joint …

This paper develops an amplify-and-forward relaying scheme for multiuser wireless
cooperative networks under frequency-selective block-fading. Single-carrier frequency …

Relaying and diversity methods improve wireless communications by jointly exploiting the
benefits of node cooperation, multiple-channel reception, and distributed processing. We …

We consider a system with a single base station communicating with multiple users over
orthogonal channels while being assisted by multiple relays. Several recent works have …
