| dc.description.abstract | 近年來，正交分頻多工存取已經成為一項廣泛應用在無線通訊系統中的技術，因為具有高度彈性的配置子載波上的資源的特性，正交分頻多工存取技術已經被很多無線通信標準所採用。
鏈路調適是一個相當熱門的研究主題且對於系統性能相當重要，而其中可適性編碼調變機制在無線通訊系統裡是最常使用的鏈路調適機制。 載波聚合這個技術在3GPP LTE系統裡扮演一個重要的角色，它可以結合多個載波元件來同時傳輸，而使用載波聚合技術的目的就是為了能夠增加傳輸的頻寬進而去增加傳輸速率。 在本論文中，我們使用了物理層抽象化的方法來幫助我們選擇對傳輸而言最好的調變編碼方式，而模擬結果顯示了若採用物理層抽象化來輔助我們選擇調變編碼方式，系統的效能會有所提升。 | zh_TW |
| dc.description.abstract | In recent year, orthogonal frequency division multiple access (OFDMA) has become a popular technique of wireless communication systems. Many wireless standards adopted OFDMA because of its flexibility of subcarrier allocation.
Link adaptation is a hot topic for research and it is very important to improve system performance. Adaptive modulation and coding (AMC) is the most common link adaption method for wireless communication systems. Carrier aggregation (CA) plays an important role in 3GPP Long Term Evolution(LTE). It is an approach to combine more component carriers to transmit at the same time, and the goal of carrier aggregation is simply to increase transmission bandwidth and further to increase transmission rate. In this thesis, we apply physical layer (PHY) abstraction to choose the best MCS for transmission and the simulation results show that the system performance is improved. | en |
