Research on BS antenna configuration in TD-LTE system
The performance of employing three typical BS antenna configurations of the TD-LTE system is evaluated in this work. Simulation result of three typical antenna configurations shows that the 0.7 λ column spacing 4 columns 8 antenna elements dual polarized smart antenna is a cost-effective way for the TD-LTE system. The UL cell average SE (SE) of 0.7 λ 8 antenna compared to 2 antenna achieves about 35.45% minimum gain. The UL cell edge SE of 0.7 λ 8 antenna compared to 2 antenna achieves about 37.93% minimum gain. The DL cell average SE of 0.7 λ 8 antenna compared to 2 antenna obtains about 7.87% minimum gain. The DL cell edge SE of 0.7 λ 8 antenna compared to 2 antenna obtains about 16.71%. minimum gain Relative to 2 antenna, the maximum coverage distance using 0.7 λ 8 antenna can be increased by 38.24%.
