研究了TD-LTE系统中双极化技术对智能阵列天线性能的影响,理论分析了下行波束赋型算法中赋型增益与信道矩阵SVD分解后的奇异值的关系,并基于相关阵信道模型利用数值计算统计出单、双极化智能阵列天线的信道特征参数。然后,通过蒙特卡洛数值仿真方法对TD-LTE系统在单、双极化智能阵列天线配置下的误块率性能进行评估。理论分析和仿真结果都表明,双极化智能阵列天线在误块率性能损失较小情况下显著减小了阵列尺寸,具有实际应用价值。

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.
