3GPP LTE 用戶端基頻收發機設計

Abstract

第四代行動電話系統是未來的趨勢，本論文根據3GPP LTE標準提出用戶端實體層收發機之架構。接收機中針對符元邊界偵測、載波頻率飄移及取樣時脈飄移之偵測及補償、cell search、通道估測、追蹤迴路、MIMO detection、碼簿選擇、渦輪解碼等演算法進行開發與研究。 論文中提出了利用PSS訊號聯合偵測整數載波頻率飄移與Sector Identity的方法。而提出的SSS訊號偵測Group Identity方法與文獻相比，可以在複雜度最低的情況下達到很高的效能。最後我們在不同的通道環境、傳輸參數下進行模擬比較，觀察提出的接收機架構之整體表現。

In this thesis, we propose a subscriber station physical layer transceiver architecture for 3GPP LTE. Algorithms for symbol boundary detection, carrier frequency offset and sampling clock offset detection and compensation, cell search, channel estimation, tracking loop, MIMO detection as well as codebook selection and turbo decoding are embedded in this receiver. We propose a method to joint detect integer carrier frequency offset and group identity. Besides, we propose a method to detect sector identity. The proposed sector identity detection algorithm not only achieves excellent detection performance but also requires the lowest complexity. In the thesis, several simulations and performances are presented and discussed in the final.
