| dc.description.abstract | 在無線通訊的環境當中，空時碼的一直是一個非常熱門的方向。對於非同調的系統而言，對於效能的改善是非常的迫切的。近年來，一種串接區塊時空碼與渦輪碼被提出。它可以在很低的訊雜比下有效率的達到很好的效能。在這篇論文之中，一個有彈性的空時調變技術被導入使用於不同長度的同調區間。而我們不僅模擬且比較了對於此調變方式的各種反覆解碼/反覆解調的檢測演算法，還提出了適用於當傳送框架的長度增長的時候，可以有好的效能以及低複雜度之演算法。 | zh_TW |
| dc.description.abstract | The space-time codes are popular topics in the MIMO wireless communication. The research of improving the performance of the noncoherent system is very important. Recently, the scheme that concatenates space-time block coding with turbo codes is proposed, which can efficiently achieve the good performance for the noncoherent block fading channels. In this thesis, a flexible space-time modulation scheme is employed for the different coherent time. Furthermore, we compare and propose several detection algorithms for iterative decoding and demodulation in the receiver side. | en_US |
