| 摘 要： | 传统的V-BLAST(Vertical Bell-lab Layered Space Time)系统是基于充分富散射环境假设,即认为收、发天线阵元之间是完全独立的,而这在宏蜂窝移动环境下一般并不成立.根据Ali Abdi等人提出的宏蜂窝MIMO(Multi-InputMulti-Output)信道模型,研究了到达角(AOA:Angle of Arrival)的非均匀分布对V-BLAST系统性能的影响.经计算机仿真分析表明:在非全向散射条件下,移动台一侧到达角分布对室外MIMO系统性能起着关键性的影响.

| Abstract: | Traditional V-BLAST systems are based on the assumption of rich-scattering environments,which means total independence between the receiver/transmitter antenna elements.Unfortunately,the independence assumption is not true under practical macro-cell mobile environments.Based on the macro-cell MIMO channel model proposed by Ali Abdi,the performance of V-BLAST systems under non-uniform distribution of angle of arrival(AOA) is presented in this paper.Simulation results indicate that the distribution of AOA on the mobile station side plays a key role in influencing the performance of outdoor MIMO systems under the condition of non-isotropic scattering. |
