摘要/Abstract

摘要： 针对循环前缀（cyclic prefix，CP）不足的情况对循环前缀通用滤波多载波（cyclic prefix-universal filtered multi-carrier，CP-UFMC）系统的影响进行了数学推导，提出了一种基于CP重构的高时间传输效率CP-UFMC接收方法来改善系统性能，并进一步研究了选择性重构方法的性能。之后仿真研究了不同CP长度，不同载波频率偏移和不同正交振幅调制阶数时的系统误符号率（symbol error rate，SER）表现。仿真结果表明，基于CP重构的CP-UFMC接收方法可以改善CP不足导致的系统SER恶化问题，使其接近CP充足时的SER，并优于对比的其他通用滤波多载波系统接收方法。

Abstract: In this paper, to address the impact of CP deficiency, a cyclic prefix-universal filtered multi-carrier (CP-UFMC) receiving method based on CP reconstruction is proposed to enhance the transmission efficiency and improve the system performance. The performance of selective reconstruction method is further investigated. Then the symbol error rate (SER) performance of the system is simulated with varying CP lengths, carrier frequency offsets and quadrature amplitude modulation orders. Simulation results show that the proposed CP-UFMC receiving method can mitigate the SER deterioration caused by CP deficiency. It effectively brings the system SER closer to the levels achieved when CP is sufficient, outperforming other universal filtered multi-carrier receiving methods.

Key words: cyclic prefix-universal filtered multi-carrier (CP-UFMC) system, insufficient cyclic prefix, cyclic prefix reconstruction, symbol error rate (SER)
