在本論文中,我們提出在無線網路之智慧型天線分集上(Smart antenna diversity)的演算法,並分析RSSI (Received signal strength index)對成功率(Success rate)的影響。因目前所有的無線系統皆有RSSI,以此來當作接收訊號的好壞依據進而影響到傳輸速率, 當我們將RSSI選擇在越好的訊號下,其可使接收品質提升,且傳輸速率也可相對提高許多。 In this paper, we propose the Smart Antenna Diversity algorithm analyze RSSI and success rate effect in wireless network. In the all wireless system have RSSI and use the quality to influence the transmission rate. We can choose the best signal. The best signal can promote the quality and the transmission rate.
