LTE中的多天線系統 2

• 结论Observations • 8天线基于EBF的波束赋型带来约7-8%的小区吞吐能力增加(increase in sector throughput with 8 element EBF compared to 4 element SU-MIMO) • 约25%的小区边缘吞吐性能增加(~25% improvement in cell edge throughput compared to 4 element SU-MIMO) î 性能仿真假设Simulation assumptions – 半波长间距多天线阵列4/8 transmit antennas with half wavele
