Performance Analysis of Smart Antenna Array with Mono-and Dual-polarization in TD-LTE System

The performance of TD-LTE system with dual-polarized smart antenna array is investigated.Firstly the beamforming gain depending on the singular value of the channel matrix is analyzed and then calculated for the mono-and dual-polarized smart antenna systems.At last the performance of the TD-LTE systems with mono-and dual-polarized smart antenna is evaluated by Monte Carlo simulation method.Both the analysis and the simulation show that the dual-polarized smart antenna pays a little penalty of slight block error ratio(BLER) loss for great decrease of antenna size and facilitation of the application of antenna array.
