| dc.description.abstract | 近幾年隨著WiMAX與UWB（Ultra-wideband）等技術崛起，3GPP為確保現有3G行動通信技術的未來競爭優勢，正致力於LTE（long term evolution）標準的制訂工作。LTE最主要的目標在於提升資料速率、增進頻譜效率、增加涵蓋範圍與降低延遲。為了增加傳輸速率採用正交分頻多工存取技術與多天線技術，且在上傳通道中為了減少功率消耗採用單載波分頻多工存取，移動性中支援超高速移動速度（350km/hr），然而本文欲探討在上傳通道中使用多天線技術來降低在移動過程中所產生的換手失敗率，進而達到更好的效能以便在一定的速度中使得連線不會中斷。 | zh_TW |
| dc.description.abstract | In recent years WiMAX and UWB technology emerges, 3GPP is now standardization process for the LTE (long term evolution) in order to guarantee the future competition advantage of existing 3G communication technology. The main targets for LTE include increased data rate、improved spectrum efficiency、improved coverage and reduced latency. In order to increase data rate adopt OFDMA (Orthogonal Frequency Division Multiple Access) and MIMO (Multiple Input Multiple Output) technology, used the SC-FDMA (Single Carrier – Frequency Division Multiple Access) to reduce power consumption at uplink, in the mobility support the ultra-high-mobility can reach 350km/hr. Furthermore, the performance evaluation used the MIMO technology to reduce handover failure for LTE uplink in mobility environment, and then reach better performance so as to will not be cut off at the certain speed. | en |
