Abstract :
In time division-high speed packet access plus (TDHSPA+) system, multiple input multiple output (MIMO) technique is adopted to improve spectrum efficiency and transmission reliability. However, most current literature are focused on the large spacing antenna setup, which is impractical for user equipment (UE) because of the size limitation. Therefore, dual polarization antenna scheme is introduced in the system to provide multiplexing gain and/or diversity gain. In this paper, we derive the dual polarization channel model for performance evaluation. Furthermore, the performance of dual polarization scheme under different MIMO architectures is presented and analyzed. It is shown that polarization scheme can achieve similar average throughput and successful transmission ratio compared with spatial separation scheme in various scenarios.
