| 摘 要： | TD-SCDMA系统通过HSUPA的引入，在上行方向上大幅地提高了数据速率。同以往的WCDMA和CD-MA2000一样，TD-HSUPA反向链路的干扰也将严重影响系统质量，但由于TD-HSUPA在上行方向上的数据信道为共享方式，且干扰控制上不能采用WCDMA中E—RGCH的方式，故对功率控制的有效性和准确性带来了挑战。分析TD-HSUPA的干扰特性，并通过系统级仿真对比几种不同功率授权算法下的系统性能。

| Abstract: | The high speed uplink packet access(HSUPA) technology in TD-SCDMA system can supply high data rate on reverse link.Similar with uplink in WCDMA and CDMA2000 system,the interference on reverse link will take great influence on signal quality.Due to the uplink share channel E-PUCH and lack of E-RGCH,the power grant will meet the challenge of gain validity and accuracy.This paper analyzes the features of interference in TD-SCDMA uplink and gives the simulation results on different power grant algorithms. |
