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.)

梯度下降法是最早最简单,也是最为常用的最优化方法。梯度下降法实现简单,当目标函数是凸函数时,梯度下降法的解是全局解。一般情况下,其解不保证是全局最优解,梯度下降法的速度也未必是最快的。梯度下降法的优化思想是用当前位置负梯度方向作为搜索方向,因为该方向为当前位置的最快下降方向,所以也被称为是”最速下降法“。最速下降法越接近目标值,步长越小,前进越慢。(The gradient descent method is the earliest and most simple and most commonly used optimization method. The gradient descent method is simple to realize. When the objective function is a convex function, the solution of the gradient descent method is a global solution. In general, the solution is not guaranteed to be the global optimal solution, and the gradient descent method is not necessarily the fastest. The optimization idea of gradient descent method is to use the current position negative gradient direction as the search direction, because the direction is the fastest descending direction of the current position, so it is also called the steepest descent method. The faster the slowest descent approach is closer to the target, the smaller the step, the slower the progress.)
