| dc.description.abstract | 在以循環字首為基礎的傳輸系統中，當循環延伸之持續期間小於通道脈衝響應之持續期間時，由於引進了符號間干擾與載波間干擾，這樣會降低系統效能。在此篇論文之中，我們提出了一種盲目波束成型演算法於不足的循環字首在單一載波分頻多工存取系統中。除此之外，我們並考慮了載波頻率偏移所造成的影響於處理方法中。這裡所呈現之模擬結果為使用單一載波分頻多工存取上行鏈結系統模型來說明所提出之演算法之功效。 | zh_TW |
| dc.description.abstract | In cyclic prefix (CP)-based transmission systems, if the time duration of the cyclic extension is shorter than the channel impulse response duration, this degrades system performance due to introducing inter-symbol interference (ISI) and inter-carrier interference (ICI). In this thesis, we propose a blind beamforming algorithm for single carrier frequency division multiple access (SC-FDMA) systems under insufficient CP scenarios. Besides, we also consider the effects of carrier frequency offsets (CFO) in the processing schemes. The simulation results are presented here by employing the SC-FDMA uplink signal model to illustrate the efficacy of the proposed algorithms. | en_US |
