dc.description.abstract | 在本文中首先介紹引導信號輔助之寬頻分碼多工存取通訊系統的重要觀念。導引信號輔助通道估測技術使上行鏈路中得以應用同調估測。通道估測技術的準確性對於同調估測而言是非常重要的。在本文中,我們提供一種比 modified weighted multi-slot averaging (WMSA) filter 更簡單的通道估測方法。比起modified WMSA filter, 這個新通道估測方法有更好的追蹤能力。 | zh_TW |
dc.description.abstract | The important concept of W-CDMA with pilot-symbol associated with each data channel is introduced. The pilot-symbol assisted channel estimation makes coherent detection possible on the reverse link. The accuracy of the channel estimate is crucial for coherent detection. In the thesis, we propose a channel estimation scheme simpler than the modified weighted multi-slot averaging (WMSA) estimation filter. The new channel estimation scheme has better tracking ability than the modified-WMSA channel estimation. | en_US |
