| 摘 要： | 具有重复信号的导言是突发通信系统中常用的同步方法。本文设计了一种新颖的参差重复导言,并给出最小均方误差的频率同步算法。与传统算法相比,该算法不仅提高了频率捕获精度,捕获范围也有效扩大且倍数可调。虽然本文仅研究了该算法在单载波频域均衡系统中的应用,但其基本原理同样适用于多载波系统。

| Abstract: | Preamble methods with same signal repetitions are often used for synchronization in burst transmission systems.A novel staggered repetition preamble(SRP) and the minimum mean square error frequency offset estimation algorithm are described in this pa- per.The proposed technique achieves a better frequency synchronization performance with sealable acquisition range compared with the conventional repetition preamble.Even though single carrier systems with frequency domain equalization(SC/FDE) are eonsidered as the application scenario,the fundamental idea is compatible with multi-carrier systems. |
