Sammanfattning

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.
