Abstract
In this contribution, the measurements conducted in an in-service Universal Mobile Telecommunication System (UMTS) network in the Minghang campus of Shanghai Jiaotong University, China, are reported. The outdoor measurement data collected in 205 locations in the coverage of a NodeB (NB) is applied to investigate the narrowband characteristics of & plusmn;45°-polarized 2×2 channels. The results show that under the empirical configurations, the cross-correlation of differently polarized channels at the user equipment (UE) side is stronger than at the NB side; the distributions of largest and second largest eigenvalues of the 4 & times; 4 polarized channel covariance matrix are well-fitted by lognormal distributions, and for the other eigenvalues Beta distributions are more appropriate. Furthermore, the statistics of the decay constant of the eigenvalues with respect to the eigenvalue indices is presented. Finally, the dependence of the capacity of a polarized channel on the condition number of the polarization correlation matrix, and inter-dependence between the condition number and the channel cross-polarization discrimination (XPD) are investigated.
