中文摘要
近年來,為了能夠提供更高的頻譜使用效率,研究者積極開發全雙工系統設計。與傳統的半雙工裝置不同之處,在全雙工的通訊裝置下,可以同時傳送以及接收訊號,因而倍增了頻譜使用率,但也造成循環干擾。在本論文中,吾人將全雙工系統應用在放大後傳送之多輸入多輸出中繼系統。吾人聯合設計了線性來源端以及中繼端之預編碼器藉以減輕自我干擾之影響。同時也考量來源端至中繼端及中繼端至目的端之通道,設計預編碼器提升點對點的效能。於此,吾人考量線性之最小均方誤差以及非線性QR連續干擾消除接收器,設計相對應預編碼器。由於預編碼器設計的最佳化問題並不是凸優化,要找到最佳解是很困難。為了找尋可行解,對於最小均方誤差以及QR連續干擾消除接收器兩種系統,我們提出了疊代方法設計預編碼器。我們首先將原始最佳化問題轉換成兩個子問題,其中一個子問題是用來計算來源端預編碼器,而另外一個則是用來計算中繼端預編碼器。藉由相關矩陣計算處理下,每一個子問題最後可得到解析解。因此,吾人根據兩個子問題的解析解,以疊代的方式計算來源端與中繼端預編碼器。此外,吾人額外針對最小均方誤差接收機之預編碼器設計,提出一種新穎低複雜度的疊代設計。在模擬結果中,可以觀察所提出之預編碼設計在各種的通道以及循環干擾的情況下,皆能有效抑制循環干擾之影響。
Abstract
Recently, the full-duplex (FD) design has received significant attention due to the ability it provides higher spectral efficiency. Unlike to the conventional half-duplex (HD) device, the FD node can simultaneously transmit and receive signals, doubling the spectral efficiency but incurring the loop-interference (LI). In this thesis, we apply the FD to the amplify-and-forward (AF) multiple-input multiple-output relay (MIMO Relay) systems. We jointly design the linear source and relay precoders to mitigate the influence of the SI and meanwhile to leverage the channel links of the source-relay and the relay-destination so that the end-to-end performance is enhanced. Herein, both the linear minimum mean-squared error (MMSE) and the nonlinear QR successive interference cancellation (QR-SIC) receivers are considered in the precoder design. Since the related optimization is inherent not convex, finding the optimum solution is difficult. To provide the tractable solution, we propose iterative methods for precoders design regarding to the MMSE and the QR-SIC receivers. In each iterative approach, we split the original problem into two sub-problem, one for solving source precoder and the other for the relay precoder. Further with some matrix manipulations, each sub-problem can finally obtain the closed-form solution by the Karush-Kuhn-Tucker (KKT) conditions. The source and relay precoders can be recursively obtained by the two sub-problems. Moreover, we additionally develop a low-complexity iterative approach for the precoders with MMSE receiver. Simulation results validate the proposed designs under various channel and LI conditions.
