设计了一种具有异周期毗邻结构的新型循环前缀,提出了相应的OFDM 频偏估计算法
设计了一种具有异周期毗邻结构的新型循环前缀,提出了相应的OFDM 频偏估计算法。该异周期毗邻结
构循环前缀由CP1 和CP2 两部分构成,使OFDM 符号具有双周期特征。通过引入较短的CP1 ,牺牲极少的资源,
可以有效克服现有频偏估计方法中的固定频偏估计范围的缺陷,同时具有频偏估计范围大,精度高的特点。(This paper proposes a heter2cycle abutted CP st ructure and a two2step OFDM carrier f requency calibration
algorithm. The cyclic prefix of the new cyclic prefix is made up of CP1 and CP2 , which provide the character of
double2cycle for OFDM symbol. By int roducing a short CP1 , the proposed algorithm can overcome the defect of
fixed f requency off set estimation range in current f requency estimation method , and achieves larger f requency esti2
mation range while obtaining fine f requency calibration.)
