摘要

本文研究了宽带移动无线电应用(如无线ATM)中单载波传输的频域均衡(FDE)同步问题。对于这样的应用,载波频率和FFT(快速傅里叶变换)窗口的时间位置必须同步。此外,信道传递函数的估计是必要的。提出了一种只用一个导频FFT符号完成所有同步任务的同步概念。

Low overhead pilot-aided synchronization for single carrier modulation with frequency domain equalization
This paper deals with the synchronization of single carrier transmission with frequency domain equalization (FDE) for broadband mobile radio applications (e.g. wireless ATM). For such applications the carrier frequency and temporal position of the FFT (fast Fourier transform) window have to be synchronized. Furthermore, an estimation of the channel transfer function is necessary. A synchronization concept is presented which uses only one pilot FFT symbol for all the required synchronization tasks.
