New wireless communications systems at 60 GHz are a promising solution to reach giga-bit data rates for short range communications, e.g., for in-flight-entertainment (IFE) systems. For shadowed 60 GHz IFE systems, high resolution and multi-antenna time-varying channel characterisation are mandatory. This paper presents the first wideband 60 GHz real-time multi-antenna channel sounder (MCS) and measurement...
Interdependences of radio-channel model parameters, being observed in some measurement data, should be reproduced by the model. For that purpose the statistical correlation is often used. From the same wideband multiple-input and multiple- output (MIMO) channel data, estimated correlation between large-scale propagation parameters (e.g. delay spread and shadow fading) could be different due to non-uniqueness...
Properties of radio-channels were quantified through appropriate measures to enable comparison between different realizations or to get suitable model representation. In past such measures are established for wideband SISO channels as well as for narrowband MIMO channels. Due to lack of joint measures, radio-channels being both wideband and MIMO are still characterized separately with wideband and...
The IST-WINNER channel model (WIM) offers a complete channel model description in a sense of large-scale as well as small-scale effects in MIMO radio-channel for B3G system designs. This paper proposes the extension of 1D regular array structures being currently supported within WIM (uniform linear array - ULA) to arbitrary 3D antenna arrays. Arbitrary antenna structures are necessary for both modelling...
The WINNER channel model is a generic model, whose scenario-specific parameters are determined from extensive wideband MIMO radio-channel measurement campaigns and results found in the open literature. This paper presents the model development during the second phase of IST- WINNER project: the model extensions toward new environments and newly supported features compromising between complexity and...
Kronecker-separable MIMO channels, especially for larger MIMO configurations, are found more often in system simulations than in reality and some good physical explanations for the latter are available. This paper treats testing Kronecker-separability from a statistical perspective. The point raised is that for larger configurations the dimensions of the full correlation matrix become too large (equal...
In this paper double-directional wideband channel measurements at 5.2 GHz and 120 MHz bandwidth for hot spot outdoor and indoor scenarios are presented. Statistical analysis based on the measurements derive spatial and temporal parameters for the recently published WINNER1 channel model. The focus is on channel models for link level evaluation and radio network planning, whereby the tapped delay line...
In this paper, we propose a novel frequency domain turbo equaliser for multiple-input multiple-output orthogonal frequency division multiplexing (MIMO-OFDM) transmission in channels where the maximum excess delay exceeds the length of the guard interval. The turbo equaliser is based on minimum mean square error filtering and utilizes the soft feedback from channel decoding for the joint separation...
