摘要 提出了一种新的适用于LTE-TDD系统的新的频偏估计算法,整数倍频偏估利用PSS自身良好的自相关性,采用滑动相关估计出整数倍频偏;小数倍频偏估计利用PSS共轭相乘的方式得到。 A new kind of frequency estimation algorithm of LTE-TDD systems is proposed, correlation of PSS itself is used by the integer frequency estimation, sliding correlation is used to estimate integer frequency offset, and PSS conjugate multiplication is applied to get fractional frequency estimation.
