Evaluation of the performance of polarization diversity estimated from measurements at one polarization

Abstract

Wireless networks are exposed to deep multipath fading conditions when they are installed in complex indoor environments. A solution to mitigate this situation could be the use of polarization diversity techniques in reception. This chapter explores this possibility, and also presents a procedure to estimate the received cross-polarized power from wide band measurements performed at just one polarization, in the 5 GHz frequency band. After testing up to three different strategies, and once analyzed the results, an improvement of 21% in terms of received power has been detected in rooms presenting strongly multipath events. © 2012 Springer-Verlag.
