隨著第三代行動電話在台灣的使用執照發出,第三代行動電話的競爭將進入戰國時代,第三代行動電話提供各式各樣的服務,為提供更好的服務品質,發展更好的技術是必要的。本論文針對第三代行動電話系統中的3GPP(Third Generation Partnership Project)寬頻分碼多重進接─分頻多工上傳鏈路系統提供智慧型天線調適性演算法,此演算法建構於現有一維犛耙式接收器上,並不需更改現有一維犛耙式接收器架構,而實現相當於二維犛耙式接收器概念之處理架構。

在論文中利用類似遞迴最小平方(RLS Like)調適性演算法,並使用最大比值合併法來合併不同路徑的訊號,以達成二維犛耙式接收器的概念。此接收器的運算複雜度比使用二維犁耙式接收機的運算複雜度低,並可用於解決〝遠近問題〞及〝抗干擾〞等問題,並能讓手機使用者減少輸出功率,因此進而減少分碼多重進接各使用者之間互相干擾,進而增加系統容量及加大覆蓋面積。

In the future, mobile communications do not only provide one kind of service. They provide many kinds of service such as voice, video, data …etc. In order to provide variable service, it must to develop new technology can provide better quality. In this paper, we present a smart antenna adaptive processing structure for the 2-D RAKE receiver design built on top of the current existent 1-D RAKE receiver. This method can be applied to the 3GPP WCDMA communication systems.
In this paper, we use the RLS-like (Recursive Lease Square-like) adaptive filter algorithm and the MRC (Maximum Ratio Combining) method to achieve the concept of 2-D RAKE processing structure. The processing structure can be used to combat the “Near-Far” problem and offer the “Interference-Resistant” property. By adopting this method, we can obtain the following advantages: 1. To decrease the transmit power to reduce mutual interference between users. 2. To increase the system capacity and coverage.
