“…In the hallway, the measured K-factors are 0.78 and 1.30 for VV and HH co-polar subchannels, respectively. Although counterintuitive, such low K-factors have been observed in previous measurements in the hallway environment [8], [9]. Under NLOS channel conditions, as expected all the subchannels follow a Rayleigh distribution.…”

In this paper, we analyze the impact of polarization diversity on the capacity of multiple-input multiple-output (MIMO) channels in indoor environments. A channel measurement campaign was conducted at 2.4 GHz to measure the co-polarized and crosspolarized subchannels under line-of-sight (LOS) and non-line-ofsight (NLOS) channel conditions. We analyze the measured data in terms of Ricean K-factor, cross-polar discrimination (XPD) and subchannel correlations. A major contribution of this paper is that in these measured channels, we observe a coincidence of low K factors and high XPD. In such channels, MIMO systems employing polarization diversity incur SNR and diversity deficits, when compared to spatial configurations. On the other hand, our results indicate that polarization diversity can substantially lower the subchannel correlations for compact configurations, even in a LOS scenario. We draw a fair comparison in terms of capacity, between spatial MIMO configurations and systems using polarization diversity. We analyze the performance of 2 × 2 and 4 × 4 MIMO configurations for a range of values of inter-element spacing.Index Terms-Polarization diversity, MIMO, dual-polarized antennas, inter-element spacing, indoor channels.

“…Although counterintuitive, we can observe from the PDP and PAS results why it has such relatively low K-factor. In previous measurements in the hallway environment [8], [9], we can also observe the same trend. And the measured K-factor of the lecture room scenario is 7.9 dB.…”

This paper presents analysis results of the wideband MIMO channel based on indoor measurements. An accurate characterization of the K-factor is very important in design issues, especially for MIMO and broadband networks. We have performed measurement campaigns for the indoor wideband channel using the Band Exploration and Channel Sounding (BECS) system developed by ETRI at 3.7 GHz with 100 MHz RF bandwidth. Based on the measured data, we analyze the Ricean K-factor characteristics of the indoor channel.

Antenna selection combined with dual-polarized antennas offers an attractive alternative for realizing higher order multiple-input multiple-output (MIMO) configurations in compact, low-complexity devices. In this paper we analyze the performance of antenna selection for narrowband dualpolarized MIMO channels with linear minimum mean square error (MMSE) receiver processing. We analytically study the impact of cross-polar discrimination (XPD) on the achieved selection gain. We use channel measurement data, collected at 2.4 GHz in a typical office environment, to compare the performance of spatial and dual-polarized MIMO channels with respect to antenna selection. Our bit-error-rate (BER) results indicate that antenna selection with dual-polarized antennas can achieve significant performance gains for compact configurations.
