    • 在先前的空時區塊編碼之相差空間調變中，使用時間排列以增加傳送速率，在本篇論文中，我們得到兩種空時區塊編碼之相差空間調變的進階結果。第一種是使用4×4空時區塊碼的相差空間調變，我們搜尋和設計符合傳送多樣性為四的交錯樣式，試圖找到最多樣式，以有高傳送速率。在另一個架構中，除了原本存在於空時區塊編碼之相差空間調變的時間排列外，我們增加了空間上的排列。透過選擇時間與空間的排列模式，比起現有的空時區塊編碼之相差空間調變具有更高的頻寬效益。

    In the previous space-time block coded differential spatial modulation (STBC-DSM), temporal permutation was employed to increase the transmission rate. In this paper, we present advanced results for two types of STBC-DSM. The first type utilizes a 4×4 space-time block code in DSM, where we search and design interleaving patterns that achieve a transmission diversity of four, aiming to maximize the number of patterns for high transmission rates. In another framework, in addition to the temporal permutation inherent in the STBC-DSM, we introduce spatial permutation as well. By selecting patterns for both temporal permutation and spatial permutation, our approach achieves higher bandwidth efficiency compared to existing techniques in STBC-DSM.
