dc.description.abstract | 目前行動數據流量以爆炸性的速度成長,為了增加網路容量,異質網路被認為是未來行動網路的候選之一。然而由於異質網路中基地台之間的傳送功率差距很大,細胞間干擾會比傳統網路更嚴重,大大地影響異質網路的效能。
傳統上功率控制及波束成型的設計目標是壓抑干擾或避免干擾,而本論文提出了一個有別於以往的概念:在強干擾的情境下刻意加大干擾訊號比使其適合做干擾消除,進而降低強干擾的影響。在考慮通道資訊不完美的情況下,針對單輸入單輸出系統及多輸入多輸出系統,本論文提出的演算法能夠根據理論位元錯誤率決定要忽略干擾或是消除干擾及對應的功率控制和波束成型。模擬結果顯示提出的方法在弱干擾及強干擾的情境下都運作良好。 | zh_TW |
dc.description.abstract | Data traffic demand in cellular networks today grows at an explosive rate. In order to increase network capacity, Heterogeneous Networks are considered to be the candidate of future cellular network. However, due to the difference of transmit power of different types of base station, the intercell interference problem becomes more severe.
Typically the design goal of power control and beamforming is interference mitigation or avoidance. This thesis introduces a totally different idea, which is artificially enhancing Interference-to-Signal Ratio (ISR) in order to do interference cancellation. Considering imperfect channel state information, the proposed algorithms for SISO and MIMO system could decide to ignore interference or cancel interference based on derived theoretical BER and design corresponding power control and beamforming. Demonstrated by simulation results, the proposed algorithm works well in weak and severe interference scenarios. | en |
