在先前的空時區塊編碼(Space-time block-coded, STBC)之空間調變(spatial modulation, SM)中，使用時間排列以增加傳送速率，在本篇論文中，我們提出兩種空時區塊編碼之空間調變(Space-time block-coded spatial modulation, STBC-SM)的排列方式以增加傳送速率。第一種是我們嘗試不對時間進行排列而是對空間進行排列，該方案被稱為具有空間排列的空時區塊編碼(STBC-SM with spatial permutation)。在第二種架構中，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，我們結合了空間上的排列。透過選擇時間與空間的排列樣式，比起現有的空時區塊編碼之空間調變具有更高的頻寬效益。該方案被稱為具有空間與時間排列的空時區塊編碼(STBC-SM with spatial and temporal permutation)。所提出的空間與時間排列可應用於其他STBC-SM方案以提高其頻譜效率。分析電腦模擬結果表明，除了頻寬效率的優勢之外，從電腦模擬可以看出，使用空間與時間排列的STBC-SM系統比原始系統提供更好的錯誤率表現。;In the previous spatial modulation (SM) with space-time block coded (STBC) scheme, temporal permutation was employed to increase spectral efficiency. In this paper, we propose two methods to further enhance the spectral efficiency of spatial modulation with STBC. The first method involves arranging antennas instead of time, termed as STBC-SM with Spatial Permutation(STBC-SM-SP). In the second framework, in addition to the temporal permutation inherent in STBC-SM, we integrate spatial permutation. By selecting patterns of temporal and spatial permutation, our proposed scheme, termed as STBC-SM with Spatial and Temporal Permutation(STBC-SM-STP), achieves higher bandwidth efficiency compared to existing spatial modulation with STBC. The introduced temporal and spatial permutations can be applied to other STBC-SM schemes to enhance their spectral efficiency. Analysis of computer simulation results demonstrates that, apart from the bandwidth efficiency advantage, the STBC-SM system with Spatial and Temporal permutations design provide better error performance than the original system.
