| 摘 要： | 本文对TD-LTE上行系统，从接收天线类型，上下行时隙配置，小区规模，系统带宽，载波频率这些不同的维度进行了广泛而详细的评估。同时在TD-LTE上行系统中对HPSS技术进行了评估。评估采用了符合3GPPE-UTRANLTE规范的系统级仿真平台。TD—LTE系统在1×8s天线配置下，性能明显优于FDD 1×2系统。TD—LTE系统小区边缘用户对小区半径更为敏感。HPSS技术更适用于大半径小区，可使平均吞吐提高40％，边缘吞吐提高62％。

| Abstract: | In this paper,profound and detailed evaluations in the TD-LTE Uplink System have been done under different assumptions such as receive antennas,UL/DL time slots,scale of cells,system bandwidth and frequency carrier.HPSS has also been researched in this system which is developed by the standard of 3GPP E-UTRAN LTE.Under the configuration of 1x8s receive antenna,TD-LTE system's performance is significantly better than FDD-LTE 1x2 and cell edge UE of TD-LTE is sensitive to the size of cell.HPSS have the highes... |
