摘要(中)

本文提出在部分頻率重複機制下的子載波配置演算法，目標為考慮使用者吞吐量總和最大化與使用者的傳輸需求量，應用在多細胞正交分頻多重接取下鏈系統。因為在多細胞網路中，將會面臨相當嚴重的細胞間干擾，使得服務品質下降，因此我們採用動態部分頻率重複機制，將子載波分為超級群組和普通群組，藉由動態地調整子載波的複用指數來提高訊號對干擾及雜訊比。
此問題可以分成兩部分來探討: 首先在頻譜配置部分，我們根據提出的配置機制，動態地將子載波分派至超級群組和普通群組。接著在子載波配置部分，我們也根據提出的配置演算法將各個子載波分配給使用者。
最後由模擬結果得知，我們提出的演算法架構能夠在系統的吞吐量與使用者的傳輸需求量，取得不錯的平衡。

摘要(英)

In this thesis, a frequency allocation scheme is proposed for multi-cell OFDMA systems in downlink, where the objective considers balancing between the maximization of the system throughput and the satisfaction of the user’s minimum data rate requirement. Due to the severe co-channel interference for cellular networks with full frequency reuse, the dynamic fractional frequency reuse scheme is adopted in the cellular network which divides all the subcarriers in each cell into two groups: super and regular groups. The dynamic fractional frequency reuse scheme can guarantee the intra-cell orthogonality and reduce the inter-cell interference. The resource allocation of the dynamic fractional frequency reuse OFDMA cellular networks on downlink transmission can be divided into two parts: frequency partition and subcarrier allocation. First, each subcarrier is assigned to either the super group or the regular group based on the utility variables and the assignment should be reused in all cells. Second, we allocate the subcarrier to users by utilizing the designed functions. The simulation results show that the proposed scheme provides a higher system throughput and improves outage compared with existing schemes.
