摘要(中)

本文針對以多傳送天線非正交多重接取具波束合成系統，提出使用者的選擇與分組演算法，讓系統總容量接近最佳解。另外我們還提出了在不同波束間的功率配置，更進一步提升系統的表現。
首先，使用者的選擇與分組方面，我們設計了一種疊代的方案，將使用者組合動態的調整以達到最大的系統總容量。另外，我們提出的疊代方案，也可以使用在別使用者選擇方法上以提升系統容量，也就是說不論起始的使用者選擇與分組如何，都可以透過套用我們提出的疊代方法來達到更好的系統表現。再者，我們提出了波束間的功率配置藉著改變功率因數以提升整個系統的效能。模擬結果顯示，我們提出的疊代方案可以接近最佳解，而計算複雜度也低於最佳解，如果以不同的初始分組加上我們提出的方案，也可以較原本表現得更好。此外，功率配置方面也得到了比原先更好的系統總容量。

摘要(英)

This thesis we propose a kind of grouping algorithm to let the sum capacity close to the optimal solution for a BF-NOMA system. In addition, we also propose the power allocation scheme between the different beams, to further enhance the performance of the system. First, we design an iterative scheme for user grouping. The paired users are adjusted dynamically to achieve the maximum system throughput. Otherwise, we propose method can also be used in other user selection methods to enhance the system sum capacity. In the other words, we can apply the proposed iteration method to achieve better system performance when we use the other user selection as the initial group. Furthermore, we propose a power allocation scheme between the beams by varying the power factor to improve the overall system performance. The simulation results show that the proposed scheme is very close to the optimal solution with a greedy search while the computational complexity is reduced. If we use a different initial group with the proposed iteration program, it can also perform outperforms the existing algorithms. The performance of use power allocation scheme is better than unused.
