    • A method for determining timing positions in a wireless communications system comprises creating a time-domain timing detection window from a preamble of a receiving signal, generating a first vector of correlations between sampling points in the time-domain timing detection window and sampling points of a known preamble, identifying a pivot position from the largest correlation value of the first vector and generating second vectors based on the pivot position, generating a third vector comprising the largest elements of the second vectors; generating a fourth vector comprising sums of elements in the second vectors, generating fifth and sixth vectors comprising a sum of subsets of the third and fourth vectors, respectively, calculating a seventh vector using the fifth and sixth vectors according to a predetermined equation, and selecting an index of one element from the fifth and seventh vectors to be the timing position according to a predetermined rule.
    • 一种用于确定无线通信系统中的定时位置的方法包括:从接收信号的前导码创建时域定时检测窗口,产生时域定时检测窗口中的采样点之间的第一相关矢量,以及 根据所述第一矢量的最大相关值识别枢轴位置,并且基于所述枢轴位置生成第二矢量,生成包括所述第二矢量的最大元素的第三矢量; 生成包括第二向量中的元素和的第四矢量,分别生成包括第三和第四矢量的子集合的第五和第六矢量,根据预定方程式使用第五和第六矢量来计算第七矢量,以及选择 根据预定规则,从第五和第七向量的一个元素的索引为定时位置。
