The next-generation wireless systems are expected to support data rates of more than 100 Mbps in outdoor environments. In order to support such large payloads, a polarized antenna may be employed as one of the candidate technologies. Recently, the third generation partnership standards bodies (3GPP/3GPP2) have defined a cross-polarized channel model in SCM-E for MIMO systems; however, this model is quite complex since it considers a great many channel-related parameters. Furthermore, the SCM-E channel model combines the channel coefficients of all the polarization links into one complex output, making it impossible to exploit the MIMO spatial multiplexing or diversity gains in the case of employing polarized antenna at transmitter and receiver side. In this paper, we present practical and simple 2D and 3D multipolarized multipath channel models, which take into account both the cross-polarization discrimination (XPD) and the Rician factor. After verifying the proposed channel models, the BER and PER performances and throughput using the EGC and MRC combining techniques are evaluated in multipolarized antenna systems.

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.
