在本篇論文中,我們提出了鏈結自適應加強型空間調變(Enhanced Spatial Modulation, ESM) 多輸入多輸出系統(Multiple-Input Multiple-Output, MIMO)下之新的預編碼設計。我們所提出的預編碼設計問題可以描述成一個non-convex的最佳化問題,近而利用連續convex 近似(Successive Convex Approximation, SCA) 方法與投影梯度(Projected Gradient, PG) 法以求得局部最佳解。模擬結果顯示,使用SCA 求解的預編碼器與使用PG 求解的預編碼器幾乎可以達到同樣的位元錯誤率(Bit Error Rate, BER) 表現,而且兩種預編碼器的設計均比現有的預編碼器設計還要好。模擬結果也顯示,使用PG求解的預編碼器之計算複雜度在現有的預編碼器之中有著最低的計算複雜度。
In this thesis, a new precoder design is proposed for linked-adaptation enhanced spatial modulation (ESM) multiple-input-multiple-output (MIMO) systems.The precoder design problem is first formulated as a non-convex optimization problem,and two design implementations using successive convex approximation(SCA) and projected-gradient (PG) method have been presented, respectively. Simulation results showed that the SCA-based precoder and the PG-based precoder achieve almost the same bit error rate (BER) performance, and both significantly outperform the existing precoder in the open literature. Simulation also shows that the PG-based precoder admits the lowest computational complexity among all the existing precoders.
