    • 在這篇論文裡，我們研究在塊狀衰退通道上的籬柵么正空時調變的設計規則。我們使用多標誌的么正空時調變訊號星座集，並針對Ungerboeck的「根據集合分割的對映」提出更適合用於籬柵么正空時調變上的設計規則。模擬結果顯示當最短錯誤事件大於2時，相較於[12]提出的設計準則，我們所使用的設計方法能夠有效的改善籬柵么正空時調變的位元錯誤率。

    In this thesis, we study the design rules of trellis-coded unitary space-time modulation over block fading channels. We use the signal constellations constructed by multiple index structure, and then we propose better design rules by making use of Ungerboeck’s idea of “mapping by set partitioning” for trellis-coded unitary space-time modulation. Simulation results show that our design rules improve the bit error probability compared to the design criteria proposed in [12] when the shortest length of error event is more than two.
