This paper addresses the optimization of upper and lower bounds on the capacity of the
multiple-input multiple-output (MIMO) relay channel. In particular, we show that evaluating …

In this paper, source and relay precoders are derived which optimize upper and lower

In this paper, we consider achievable rates for the Gaussian multiple-input multiple-output
(MIMO) relay channel that can be obtained with the relay using the partial decode-and …

In this paper, the capacity of MIMO relay channel with decode and forward (DF) scheme is
investigated, where each node within the system quipped with multiple antennas and …

An iterative algorithm is proposed to achieve the optimal rate region in a two-way relay
channel, where two nodes want to exchange data with each other using multiple relays, and …

We study the capacity of multiple-input multiple-output (MIMO) relay channels. We first
consider the Gaussian MIMO relay channel with fixed channel conditions, and derive upper …

This paper addresses the problem of source and relay transmit covariance optimization on
the Gaussian MIMO relay channel with full channel state information (CSI), ie, assuming …

Relay channels have been extensively studied in the literature since the seminal paper by
Cover and El Gamal. Nevertheless, characterizing the capacity of relay channels still …

This paper deals with the superposition coding (SPC) scheme in multiple-input multiple-
output two-way relay channels subject to imperfect channel estimation. In this scenario, two …

Relay channels plays a central role in next-generation multihop wireless systems. This
paper considers the MIMO relay channel where multiple antennas are employed by each …
