| 针对TD-SCDMA系统的数据传输速率低的问题，提出了TD-SCDMA HSDPA增强型系统。本文建立了该系统终端的基带数据流模型，并对在不同调制方式下和重发次数时系统的吞吐量和信道中断概率进行了研究，结果表明系统采用的调制方式编码速率越高，系统的吞吐量和信道中断概率越差。 |

| Abstract: |
| As for the problem of low data transfer rate exists in TD-SCDMA, an enhanced system—TD-SCDMA HSDPA is presented. This paper establishes a baseband data flow model for the system terminal, and investigates the system’s throughput and channel outage probability, according to the different modulation schemes and retransmit times. The result shows that the higher the system’s modulation scheme coding rate, the worse the system’s throughput and channel outage probability. |
