We design novel transmission strategies to maximize the energy efficiency (EE) of the uplink
multi-user multipleinput and multiple-output relay channel. In this channel, K multi-antenna …

In this letter, we investigate the energy efficiency (EE) maximization problem in multiuser
amplify-and-forward (AF) MIMO relay systems with a holistic power model. A low complexity …

In this paper, we consider a non-regenerative MIMO two-way relay system with imperfect

The problem of jointly optimizing the source precoder, relay transceiver, and destination
equalizer has been considered in this paper for a multiple-input-multiple-output (MIMO) …

The energy efficient joint source-relay power allocation problem is studied for the multi-input
multi-output (MIMO) amplify-and-forward two-hop relaying system, in which the objective of …

This paper studies the precoder design of bidirectional networks in which each node is
equipped with multiple antennas. In contrast to the conventional model of bidirectional relay …

For nonregenerative multihop multiple-input multiple-output (MIMO) relay communication
systems, the optimal source precoding matrix and the optimal relay amplifying matrices have …

In Part II of this two-part paper, a sum-rate-maximizing power allocation with minimum power
consumption is derived for multiple-input multiple-output (MIMO) decode-and-forward (DF) …

In this letter, we investigate the antenna selection in decode-and-forward (DF) MIMO relay
systems where the circuit power consumption is considered. The main problem is that the …

Energy-efficient resource allocation in a single-user, amplify-and-forward (AF), relay-
assisted, multiple-input-multiple-output (MIMO) system is considered in this paper. Previous …
