This paper provides an overview of the state-of-the-art radio propagation and channel
models for wireless multiple-input multiple-output (MIMO) systems. We distinguish between …

We introduce the concept of the double-directional mobile radio channel. It is called this
because it includes angular information at both link ends, eg, at the base station and at the …

We measure the capacity of multiple-input multiple-output radio systems in microcellular
environments. We use a new data evaluation method that allows to evaluate the cumulative …

We devise theoretical grounds for constructing channel models for multiple-input multiple-
output (MIMO) systems based on information-theoretic tools. The paper provides a general …

This contribution presents an extension of the SAGE (space-alternating generalized
expectation-maximization) algorithm originally published in Fleury et al.(1999) that allows for …

For the simulation and design of smart antenna transmission principles in mobile radio,
precise knowledge of the time—variant directional multipath structure in various radio …

We present a statistical analysis of wideband three-dimensional channel measurements at
base station locations in an urban environment. Plots of the received energy over azimuth …

This paper describes three-dimensional (3D) radio channel measurements at the base
station site in an urban environment. We introduce a measurement concept which combines …

We measured the spatial properties of the three-dimensional (3D) double-directional radio
channel in urban macrocell environments separately at both ends of the link. In this paper …

This contribution discusses which information can be derived from estimated directions of
arrival (DOAs) and directions of departure (DODs) from a multiple-input multiple-output …
