Distributed antenna systems (DAS) has been adopted in both indoor and outdoor wireless communications for benefits of reducing the power consumption and enhancing system capacity owing to spatial multiplexing gains. The capacity of a DAS system is partially determined by the cross-correlation of the large-scale fading of multiple links in the system. In this contribution, we use experimental data...
Spatial auto- and cross-correlation characteristics of propagation channels are investigated for four indoor scenarios using measurement data. In addition to the well-known spatial auto-correlation effect, significant cross-correlation between channels is also observed. We found that non-zero spatial cross-correlation among channels may occur in three scenarios with possibly different mechanisms....
Based on the experimental results obtained from the extensive wideband MIMO channel measurements at 2.38, 3.705 and 5.25 GHz in Line-Of-Sight (LOS) rural macro environments, the empirical Path Loss (PL) model is proposed for the IMT-Advanced systems. PL exponent, intercept, frequency dependent factor and standard deviation of Shadow Fading (SF) are obtained by using the Least Square (LS) method. It...
