    Abstract: 有別於全向性天線,方向性天線與聰明天線的空間多樣性(Spatial Diversity)帶來空間利用率的優勢,而聰明天線於同一時間內多個電束波(beam)具有同時傳送或同時接收的好處,更可提昇網路中整體傳輸效能。然而,多個電束波的傳送若無完善的排程,卻也可能產生更多干擾,以致於網路整體效能不增反減。因此本研究將針對聰明天線的傳輸需求提出一有效排程,充份利用聰明天線的優勢及特性,使傳輸所需的等待時間大幅減少,並使平行傳輸對能達到最大化,進而達到提昇網路整體傳輸效能的目的,於實驗也顯示,本論文所提出之演算法對於減少傳送時間較方面有較好的表現。
    The directional and smart antenna systems are different to the omni-directional antenna system. The major difference is the spatial diversity and the better channel utilization. The smart antenna system can communicate with multiple targets through handling the different beams. However, the interference is being between the different beams. The good scheduling will be the key of the performance of transmission throughput. For this reason, we proposed a novel scheduling algorithm to arrange the transmissions between different beams. Our contributions are shorter waiting time and more transmission pair in parallel. We also got the good throughput in the simulation.
