摘要(中) 論文摘要
本論文針對時空籬柵編碼,擬以多層次編碼(multilevel coding)技術來降低其複雜度,第三章以全多樣性(full diversity)之時空編碼為主題,採用[4]中的一個碼,來設計三個傳送天線的時空區塊編碼,並改變星座圖的符號標記法(labeling),以計算時空碼的行列式值(determinant)的方式,研究符號標記法與錯誤率效能的關係,並以此架構轉換成一時空籬柵編碼的架構,試圖找出除了延遲多樣性架構之外,設計時空籬柵編碼的準則。
第四章以非全多樣性的時空編碼為出發點,觀察在增加傳輸率的同時,相較於時空籬柵編碼錯誤率效能的下降幅度,研究其原因,並研擬改進的方法。摘要(英) This thesis is aimed at space-time trellis coding, using multilevel coding technology to decrease complexity. Chapter 3 focuses on full diversity space-time codes, using a code in [4] to design a space-time block code which has three transmission antennas. We try to change signal labeling and calculate determinant in order to research error performance and transform this structure to a type of space-time trellis codes. Try to find a design method to construct space-time trellis codes instead of delay diversity scheme.
Chapter 4 focuses on non-full diversity space-time codes which increase transmission rate and reduction of observe error performance. We also compare with space-time trellis coding in order to obtain more insights and improve its error performance.關鍵字(中) ★ 時空編碼
