Capacity of MIMO systems based on measured wireless channels
Författare
Summary, in English
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
distribution function of the capacity from a single measurement.
This method is based on an extraction of the parameters of the
multipath components and, thereafter, a synthetic variation of
their phases. In the analyzed environments, we find capacities to
be about 30% smaller than would be anticipated from an idealized
model. In addition, the frequency selectivity of the channel makes
the cdf of the capacity steeper and, thus, increases the outage
capacity, compared with the frequency-flat case, but the influence
on the mean capacity is small.
