| dc.description.abstract | 現有的多點協作(CoMP)技術是使用正交多工(OMA)，其中最為大家所廣泛使用的是聯合傳輸(JT)。但是JT-OMA會隨著細胞邊緣使用者的數目增加而降低其頻譜效益。剛好最近很熱門的非正交多工(NOMA)可以有效率地和現有的CoMP技術結合在一起來同時提升細胞邊緣使用者的傳輸速度和頻譜效益。
在這篇論文中，於上行的情境中，我們所提出的SC-NOMA在所有的訊號雜訊比範圍中，提供了比傳統JR-NOMA還要高的細胞邊緣總和傳輸速度。另外在下行的情境中，我們所提出的混合式JT+SC-NOMA在所有的訊號雜訊比範圍中，提供了比傳統JT-NOMA還要高的細胞邊緣總和傳輸速度。此外，我們所提出的α-fairness JT-NOMA和PR-based NOMA可以大幅增進使用者公平性且同時不會犧牲太多的細胞邊緣總和傳輸速度。 | zh_TW |
| dc.description.abstract | Non-orthogonal multiple access (NOMA) can be effectively integrated in coordinated multipoint (CoMP) mobile networks to enhance transmission performance and spectral efficiency at cell boundaries. In this paper, a strong-channel-selection NOMA (SC-NOMA) scheme is proposed to achieve better throughput than joint-reception NOMA (JR-NOMA) scheme for uplink CoMP networks and comparable throughput than joint-transmission NOMA (JT-NOMA) scheme for downlink CoMP networks. Hybrid JT+SC-NOMA scheme that combines strong-channel-selection and joint-transmission strategies is also proposed to provide prevailing throughput for downlink CoMP networks. Moreover, the α-fairness JT-NOMA scheme and the product-rate-based NOMA (PR-based NOMA) schemes are demonstrated to provide comparable system throughput to the sum-rate-based NOMA schemes while yielding better user fairness. | en |
