This paper investigates the channel estimations in a relay network with multiple transmit and
receive antennas, including the estimation of the end-to-end channel matrix and the …

We consider the problem of enhancing Quality-of-Service (QoS) in mobile relay
beamforming networks, by optimally controlling relay motion, in the presence of a dynamic …

Bit error rate (BER) and outage probability for amplify-and-forward (AF) relaying systems
with two different channel estimation methods, disintegrated channel estimation and …

In this letter, we consider a bi-directional relay network in which two users, U 1 and U 2,
exchange their information via a relay station, RS. Multiple antennas are deployed at both …

In this paper, we investigate the effects of channel estimation error on the receiver of multiple-
input-multiple-output (MIMO) amplify-and-forward (AF) two-way relaying. The estimation is …

In this paper, we investigate the individual channel estimation over the three-node one-way
relay network, where all the nodes are equipped with multiple antennas. We first examine …

This paper provides symbol-error-rate (SER) performance analysis and minimum power
allocation for multi-source multi-destination cooperative vehicular networks using the hybrid …

In this paper, we investigate power-allocation and relay-selection algorithms for amplify-and-
forward (AF) cooperative relay systems under imperfect channel estimation. Based on …

Cooperative relaying and dynamic-spectrum-access/cognitive techniques are promising
solutions to increase the capacity and reliability of wireless links by exploiting the spatial and …

In this paper, we consider a multicarrier asynchronous bidirectional relay network, where
different relay-transceiver links can cause different delays in the signals they convey …
