摘要:

本文利用正交频分复用（OFDM）帧结构的特点，引入代价函数，推导出了一种符号同步算法和频偏估计算法，并从理论上分析了在存在频偏的情况下，符号同步可以独立于频偏估计。计算机仿真表明，该算法具有较好的同步和频偏估计性能。

An Algorithm of Symbol Synchronization and Frequency Offset Estimation for OFDM Based on the Cost Function

()

Abstract:

In this paper an algorithm of symbol synchronization and frequency offset estimation for OFDM based on the cost function is proposed. The algorithm is derived from a cost function, which is based on the character of the OFDM signal frame structure. Theoretical analysis shows that the symbol synchronization is independent from the frequency offset estimation when frequency offset exists. The simulation results indicate that the proposed algorithm has good performance.
