This paper evaluates the performance of widely linear filtering based equalization for suppression of kindred co-channel interference. The presented approach is extension of the MMSE method proposed for ICI/ISI compensation for OQAM/FBMC transmission system in [1][2]. The analysis and computer simulation results show the relevance of widely linear filtering based equalization approach when the interfering...
This paper proposes 2×2 MIMO OQAM/FBMC receiver strategy based on successive interference cancellation (SIC) as an extension of the SISO approach which uses entirely real-valued formulation of the transmission system model]. Both increase of throughput and SNR gain are observed through appropriate maximum ratio combining (MRC) of the soft symbols pertaining to the receiver-end diversity branches....
In this paper, we study the spatial structure of multiple-input multiple-output (MIMO) links in small urban macro-cells at 2.6 GHz. We resolve the double-directional structure of the radio channel. Also we compute common metrics used to characterize MIMO links, i.e. the structure of singular values and the resulting capacity. In a line-of-sight (LOS) link, we find that local scattering is not enough...
The stochastic equivalence with the realistic radio propagation environment is a crucial assumption behind geometry-based stochastic channel models (GSCM). Within the 3GPP SCM and WINNER models, the global properties of the underlying stochastic process are expressed by Large-Scale Parameters (LSP), describing the distribution of the transmitted power over different dimensions of the channel. In this...
Novel channel models as from COST 273 and IST-WINNER projects are models to evaluate the performance of multi-antenna concepts under link-level and system-level. For consistent performance evaluation the channel models needed to be parameterized by multipath parameters based on measurements. It seems these parameters can be grouped into geometrically co-located paths, so called clusters. The reliability...
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...
This paper is summarizing and comparing properties of channel models used for Beyond-3G (B3G) MIMO simulations: 3GPP spatial channel model (SCM), its extension (SCME), and models developed by WINNER. Compared models are offering complete channel model description in a sense of large-scale as well as small-scale effects in MIMO radio-channel. WINNER targeted model was supposed to provide reliable tool...
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...
