Polarization diversity in indoor scenarios: an experimental study at 1.8 and 2.5 GHz

The paper presents the results of a set of measurements carried out in order to research the behaviour of a polarization diversity scheme in indoor environments in the 1.8 and 2.5 GHz bands. To this end, parameters such as the cross-correlation coefficient and the cross-polarization discrimination between the individual signals received in each of the combiner branches are analysed. By simulating various types of combiners, the improvement produced by the combination in the statistical behaviour of the signal, and the decrease of the bit error rate after the combination are also analysed.
