基于并行干扰抵消的UFMC系统信道均衡

UFMC System Channel Equalization Based on Interference Cancellation

中文摘要英文摘要

通用滤波多载波(UFMC)技术作为5G的一种候选波形,传输中不加循环冗余(CP),多径衰落信道下会产生符号间干扰(ISI)以及子载波间干扰(ICI)。本文首次分析了多径信道下UFMC系统的干扰情况,在采用迫零均衡后,对可靠区间外的数据,根据剩余干扰表达式,近似重构相邻载波及符号间干扰,最后对各载波并行地进行迭代干扰抵消。仿真结果表明,在多径信道下,本文的方法相比传统的单抽头以及最小均方(LMS)均衡方法能够更好地降低误码率,提高系统性能。

Universal Filtered Multi-Carrier (UFMC) technology is a candidate for 5G with no cyclic redundancy (CP) in transmission and intersymbol interference (ISI) and intercarrier interference (ICI) under multi-path fading channels. In this paper, the interference of UFMC system under multipath channel is analyzed for the first time. After the zero-forcing equalization is adopted, the data outside the reliable range are reconstructed according to the residual interference expression, and the adjacent carriers and intersymbol interference are reconstructed. Finally, Iteration interference cancellation. The simulation results show that the proposed method can reduce the bit error rate and improve the system performance better than the traditional one-tap and least mean square (LMS) equalization methods under multipath channel.
