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 …

In this paper we discuss and compare different signalling and routing methods for multiple-
input multiple-output (MIMO) relay networks in terms of the network capacity, where every …

This paper presents an analytical characterization of the ergodic capacity of amplify-and-
forward (AF) MIMO dual-hop relay channels, assuming that the channel state information is …

We consider three-node wireless relay channels in a Rayleigh-fading environment.
Assuming transmitter channel state information (CSI), we study upper bounds and lower …

Performance of multi-hop MIMO relay channels under the amplify-and-forward and decode-
and-forward protocols are compared via the capacity and SNR gains. In an N-hop channel …

A Gaussian orthogonal relay model is investigated, where the source transmits to the relay
and destination in channel 1, and the relay transmits to the destination in channel 2, with …

We determine the capacity region of a degraded Gaussian relay channel with multiple relay
stages. This is done by building an inductive argument based on the single-relay capacity …

We study the impact of multiple linear amplify-and-forward relays on the capacity of rank-
deficient MIMO channels. We derive a general system model for wireless networks with one …

The spectral efficiency of mobile radio networks can be improved by allowing each mobile
station to act as a relay for one other mobile station. One can expect further performance …

We consider slow fading relay channels with a single multi-antenna source-destination
terminal pair. The source signal arrives at the destination via N hops through N-1 layers of …
