In cellular networks, base stations can cooperate in order to bring spatial diversity.
Cooperative diversity enables to increase link capacity and signal to noise ratio. This paper …

The effect of relaying in terms of energy efficiency is an important and interesting issue in
cellular communications. In this paper, two relaying schemes for uplink are analyzed and …

We present a simulation study of two relaying schemes in downlink cellular systems. We
simulate the performance of two relaying strategies:(i) a collaborative power addition (CPA) …

Multihop cellular networks employ relay stations to enhance end-to-end link quality in terms
of capacity, coverage and reliability. Techniques like cooperative relaying and spatial reuse …

We propose in this paper, a strategy to minimize the total transmit power in a decode-and-
forward (DF) multi-user, multi-relay cooperative uplink, such that each user satisfies its data …

Cooperation among network nodes provides transmit diversity in cases where wireless
transmitters, due to size and power limitation, cannot support multiple antennas. We …

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 …

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 …

Previous work on cooperative cellular networks has mostly considered homogeneous
relaying architectures where all nodes act as both sources and relays. In this paper, we …

We consider a wireless network with one source/destination pair and several linear amplify-
and-forward relays. The influence of the gain allocation at the relays on the performance in …
