SISO polarized flat fading channel modeling for dual-polarized antenna systems

Abstract

The next-generation wireless systems are expected to support data rates of more than 100 Mbps in the outdoor environment. In order to support such large payloads, the polarized antenna can be employed as one of candidate technologies. Recently, the third generation partnership standards bodies (3GPP/3GPP2) have defined a cross-polarized channel model in SCM-E for MIMO systems, but this model is quite complex and too many parameters are included. The SCM-E channel model generates only single channel output for each time instant, therefore it is not so appropriate to apply the SCM-E channel model directly to MIMO spatial multiplexing or receive combining systems. In this paper, we provide practical but simple dual-polarized channel models, which take into account both cross-polarization discrimination (XPD) and Rician K-factor. We verify the proposed channel model by observing the XPD and correlation values among polarized channels. In addition, BER & PER performances and system throughput using MRC and EGC combining at Rx side are simulated in this paper. The simulation results show the dramatically increased system throughput by the adoption of dual-polarized antenna.

Practical and Simple Wireless Channel Models for Use in Multipolarized Antenna Systems

“…As shown in Figure 1, the MS mobility is taken into consideration in regard to the polarized antenna channel model found in [11]. is the phase rotation of the received signal at the MS due to the scatterers, and is the updated phase rotation according to the MS movement, as described by where is the radius of the scatterers and Δ is the moving distance of the MS for a 1-packet duration (e.g., 5 us).…”

“…In addition, according to the scatterer environments, they are further classified into a 2D channel model and a 3D channel model. The PS multipolarized channel models are based on SCM-E channel model given by (11). It is a well-known 2D PMIMO channel model, which obtains only a single complex output resulting from the combination of all the polarized links.…”

“…In our preliminary work [11], we suggested the dualpolarized channel model mainly based on the 2D scattering scenario. In order to complete our research work, in this paper, a practical and simple (PS) wireless channel model for use in multipolarized (i.e., dual-/triple-polarized) antenna systems based on both 2D and 3D scattering scenarios is presented.…”

“…In related works, the authors in [7] provided a comparison of several multipolarized MIMO models and also presented some useful results in terms of channel capacity. In [8], the authors showed that the use of polarization diversity with a combining method enhances the capacity of wireless communication systems. Oestges et al in [1] studied the advantages of using DP antenna arrays in a multiple channel environment.…”

“…Especially in the multiple-inputmultiple-output (MIMO) systems, for saving the space, dual-polarized antennas are usually used to substitute two space-isolated singlepolarized antennas [6]. Such polarized MIMO antennas have been proved to show the advantages of increasing spectrum efficiency, mitigating polarization mismatch between the transmitter and the receiver, improving the channel capacity and diversity gain [7][8][9].…”
