Characteristics of narrow band dual-polarized MIMO over satellite channel model

Land Mobile Satellite (LMS) communication system has been playing a significant role in wireless broadcasting and communication network. Dual-polarized Multiple-Input Multiple-Out (MIMO) technology can be applied to LMS to enhance the spectrum efficiency and capacity. In this paper, a statistical model is designed to simulate the channel characteristics by analyzing the large scale fading and small scale fading components. Important channel factors are considered and analyzed including temporal and polarization correlation, Doppler Shift effect, cross-polar discrimination (XPD), cross-polar coupling (CPC) and angle of arrival. The channel statistical characteristics and outage capacity are simulated and to verify that dual-polarized MIMO technology can improve systematic performance of traditional LMS system.
