16591 第1层充分考虑重叠特性,结合前面重叠数据块进行初步优化, The first layer takes full account of the overlap characteristics and combines the previous overlapping data blocks for initial optimization.
16592 第2层对数据块进行分组,在每组选择对峰值影响最大的数据块进行优化,来减少进行相位因子搜索的数据块数量,并且在第1层优化中缩小相位因子的搜索范围,以降低系统的计算复杂度。 The second layer groups the signals, and in each group, the data blocks that have the greatest impact on the peak value are optimized to reduce the number of data blocks for phase factor search. The search range of phasefactor is reduced in the first layer optimization to reduce the calculation complexity.
