OFDM系统中基于零子载波检测的频偏估计模糊度校正算法

A Novel Frequency Ambiguity Resolution Algorithm in OFDM Systems Based on Null Subcarrier Detection

  • 摘要: OFDM系统的性能对频率偏移非常敏感。该文针对频偏估计中所产生的模糊度问题提出了一种基于零子载波检测的频偏估计模糊度校正算法。它利用OFDM符号中不传输信息的子载波进行频偏估计模糊度校正。文中分析了定时误差对算法性能的影响并分析比较了算法的复杂度。仿真结果表明,在性能相近的前提下,该文提出的频偏估计模糊度校正算法与传统的算法相比具有运算量小的优点。
