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。 | zh_TW |
| dc.description.abstract | 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. | en_US |
