Abstract
In this paper, an advanced closed loop polarized Multiple-Input Multiple-Output antenna system employing Pre-RAKE and Combined Transmit Diversity techniques “Polarized MIMO Pre-RAKE CTD system ” is proposed in Frequency Division Duplex (FDD) mode. The proposed system introduces a significant performance gain without increasing the complexity and the power consumption of the mobile terminal as well as reducing the spatial dimensions of the MIMO system. In this paper, our system will be compared with both the MIMO Pre/Post RAKE system and the Vertical MIMO Pre-RAKE CTD system. The effect of the crosspolarization discrimination (XPD), the envelope correlation (ρ env) and the Co-polarization Power Factor (CPF) on the BER performance will be discussed. Also, the system performance will be investigated under different Feedback Information (FBI) rates. In addition, a performance comparison for the vehicular and the pedestrian environments will be presented.
