Doctoral Thesis / Dissertation from the year 2008 in the subject
Electrotechnology, grade: summa cum laude, Technical University of
Ilmenau, 152 entries in the bibliography, language: English,
abstract: This thesis deals with Experimental Channel
Characterisation and its performance limits in real propagation
environments. This includes recording of the multidimensional
wideband channel matrix by using a MIMO channel sounder and antenna
arrays at both sides of the link. High-resolution parameter
estimation is finally applied to characterise the channel in terms
of DoD, DoA, TDoA, and complex polarimetric path weights. The
quality of these estimates in "real world" scenarios is degraded by
several impairments of the practical antenna arrays and the
measurement system used. The resulting estimation quality limits
are investigated in detail by simulations and measurements. The
entire processing chain is analysed in terms of possible error
sources. To this end, measurement system impairments, antenna array
calibration errors as well as limitations of the radio channel
model comprising two parts: specular like reflections (SC) and
distributed diffuse scattering (DMC) applied by the high-resolution
parameter estimation procedure are investigated. Moreover,
consequences of using these results to deduce and parameterise
geometry based channel models are demonstrated. The contributions
of this thesis are of interest for researchers dealing with
high-resolution parameter estimation and channel modelling and can
be summarised as follows: the efficient and accurate radiation
pattern modelling of antenna arrays, the powerful performance
evaluation framework for practical antenna arrays, the exposure of
consequence of modelling errors on parameter estimation, and the
demonstration of overall limitations of Experimental Channel
Characterisation.
