摘要/Abstract

摘要：

对多频带正交频分复用超宽带系统同步技术进行研究，提出一种基于时域扩展技术（TDS）的盲载波频偏（CFO）跟踪算法。利用数据符号与其时域扩展符号的特殊映射关系，在时域和频域分别推导出残余载波频偏的盲估计公式，并构建相应的时频跟踪环路。仿真结果表明，该盲算法具有比导频辅助法更优的跟踪性能。10dB信噪比下，基于TDS进行时频跟踪的残余CFO均方根误差均达到2×10^-4，系统误比特率可达10^-6数量级。

Abstract:

A blind carrier frequency offset (CFO) tracking algorithm based on time-domain spreading (TDS) was proposed for multiband orthogonal frequency division multiplexing ultra wide band systems.The scheme uses data symbols and the mapped TDS ones to develop time and frequency-domain estimators and tracking loops respectively.Simulation results indicate that the proposed scheme has a better performance in tracking accuracy than pilots-aided ones.Under the SNR of 10dB,the mean square root errors of the residual CFO reach 2 10^-4,and the bit error rate of the system is 10^-6× of magnitude.
