摘要
单载波频域均衡(SC-FDE)技术是一种能有效对抗无线传输多径效应的方法。根据SC-FDE系统中2UW帧结构的特殊性质,在多径延迟不是很大的慢时变传输条件下,对一般的LS和基于DFT的信道估计方法进行改进,提出了一种适合SC-FDE系统的估计方法。仿真分析显示,这种方法可以带来较好的性能增益。
Single-carrier frequency domain equalization (SC-FDE) is an efficient method against multipath effects of wireless transmission. According to the special nature of the 2UW frame structure in the SC-FDE system, considering the situation of not too large a multipath delay and slow time-varying, a method is proposed to improve the LS and DFT-based channel estimation, which is suitable for SC-FDE system. Simulation and analysis shows that the new method can result in a better performance.
