| dc.description.abstract | 正交頻分複用（OFDM）技術是第四代移動通信系統中最重要的調製技術之一。 OFDM系統具有結構簡單，傳輸速率快，頻帶利用率高，抗衰落能力強，符號間干擾能力強等優點。 然而，隨著第五代無線通信的發展，OFDM系統存在一些缺點：矩形窗口帶外衰落非常慢，循環前綴（CP）導致低頻譜效率等。為了滿足第五代移動通信系統，人們提出了一種新的調製技術-濾波器組多載波（FBMC）。
在本文中，我們首先比較在有載波頻偏和延遲估計的情況下，不同通道下FBMC系統之不同原型濾波器的性能，然後我們確定哪種原型濾波器對於FBMC系統是最好的。 | zh_TW |

The Orthogonal Frequency Division Multiplexing (OFDM) technology is the one of the most significant modulation technology of the fourth generation mobile communication system. OFDM system has variety advantages such as simple structure, high transmission rate, high utilization rate of the frequency band, anti falls ability and resistance to inter-symbol interference. However, with the development of the fifth generation wireless communication, there are some disadvantages of OFDM systems: the rectangular window out of band fade is very slow and the cyclic prefix (CP) leads to low spectrum efficiency, etc. To satisfy the fifth generation mobile communication systems, people proposed a new modulation technology-filter bank multicarrier (FBMC).
In this paper, we first compare the performance of different prototype filters for FBMC systems under different channel with the Carrier Frequency Offset and Delay estimation and then we determine which prototype filter is the best for FBMC systems. | en_US |
