摘要

正交分頻多工(Orthogonal frequency-division multiplexing, OFDM)是目前4G通訊系統正在使用的的無線通訊技術。為了因應使用者越來越多，以及追求更快速的通訊系統，在下一代5G通訊系統中考量了商業用途，所以利用OFDM為基礎往下研發。
本篇論文加入了循環前綴，而使得CP-OQAM-OFDM系統具有更好的穩定性，利用循環前綴或著循環後綴不同的方法，來設計一種適合5G網路的通訊系統，本篇論文也探討了CP-OQAM-OFDM在COST 207的環境下的性能，透過模擬結果計算的錯誤率來比較加入了循環前綴過後的性能是否適合未來5G網路的需求。

Orthogonal frequency division multiplexing (OFDM) is a wireless communications technology 4G communication system is being used. In response to the growing number of users, and the pursuit of faster communication system, a communication system in the next generation 5G considered a commercial use, so the use of OFDM-based research and development down.

This paper added a cyclic prefix,and makes the CP-OQAM-OFDM system has better stability, the use of cyclic prefix or the cyclic suffix different ways to design suitable 5G communication system, this paper also explored the CP-OQAM-OFDM performance in an environment of COST 207, the error rate calculated by the simulation results to compare the performance of the cyclic prefix is added after the suitability of future 5G network needs.
