| 摘 要： | HSDPA(High Speed Downlink Packet Access：高速下行分组接入)是第三代移动通信系统WCDMA(Wideband Code Division Multiple Access)的演化技术。本文提出应用信道载干比预测技术，为HSDPA系统提供信道的将来信息，从而减小实际中载干比估计的误差。仿真结果表明信道预测技术可以有效提高系统的吞吐量。

| Abstract: | HSDPA(High Speed Downlink Packet Access)is the evolution version of WCDMA. The drawback of the technology used in HSDPA to overcome the fast fade in mobile communication channel is discussed. A scheme based on channel prediction is proposed to remove the obstacle mentioned above. Simulation results prove that the proposed prediction algorithm can effectively improve the throughput of HSDPA system. |
