Relationship between Cross-Polarization Discrimination (XPD) and Spatial Correlation in Indoor Small-Cell MIMO Systems

چکیده
In this letter, we present a correlated channel model for a dual-polarization antenna to omnidirectional antennas in indoor small-cell multiple-input multiple-output (MIMO) systems. In an indoor environment, we confirm that the cross-polarization discrimination (XPD) in the direction of angle-of-departure can be represented as the spatial correlation of the MIMO channel. We also evaluate a dual-polarization antenna-based MIMO channel model and a spatially correlated channel model using a three-dimensional (3D) ray-tracing simulator. Furthermore, we provide the equivalent distance between adjacent antennas according to the XPD, providing insights into designing a dualpolarization antenna and its arrays.

Performance of Spatial Multiplexing and Transmit Diversity in Multi-Polarized MIMO Transmissions with Receive Antenna Selection
In this work, we consider the use of multiple antenna signaling technologies, specifically space-time block coding (STBC) and spatial multiplexing (SM) schemes, in multiple-input multiple-output (MIMO) communication systems employing dual polarized antennas at both ends. The use of dual-polarized antennas theoretically double the number of virtual antennas used in the system. On the other hand,...

This paper presents measurement results at 2.3 GHz for multiple-input multiple-output (MIMO) systems applying multiple polarized antenna arrays and single polarized uniform linear arrays (ULAs). The measurements were taken indoor in two different buildings, outdoor between a base station on the rooftop and a mobile station in a car, as well as between two mobile stations in two cars (C2C). Meas...
متن کاملOn the Modelling of Polarized MIMO Channel
This paper presents a simple model for polarized multiple-input multiple-output (MIMO) channels. At first, the model is desired for line-of-sight (LOS) scenario, and then generalized for non-LOS (NLOS) case. The analysis of the crosspolarization discrimination (XPD) for a 2×2 MIMO systems shows that the XPD depends on both the antenna patterns and the polarization mismatch between the transmit ...

A pair of small and low profile dual-polarization antennas has been developed for miniature indoor base station under the MIMO (Multiple-Input Multiple-Output) technology to restrain spatial correlation in LOS (Line-Of-Sight) channel environment. Both of the component antennas operate at 2GHz, it is expected to apply on IMT-2000 or LTE communication systems. The space volume is about W150×H120×...
متن کاملExtended Ellipse Model for Multi-Polarized MIMO Antennas
This work presents a quasi-three dimensional scattering model to predict the polarization properties of an indoor radio channel. The proposed model considers not only the effect of the polarization of fields scattered by scatterers but also extends the ellipse model to a quasi-three dimensional model. In the model, all scatterers are considered as a patch scatterer and distribution properties o...
