Compared with the DPSS,instead of solving the problem of matrix eigenvalues, the multitaper in this paper needs less calculationwith intuitionistic and analytical expression of tapers.
与离散长球序列多窗口相比，此方法得到的多窗口具有直观的解析表达式而无须求解矩阵的特征分解问题，因而具有较小的计算量。
It is indicated by the performance analysis that the approach here has comparative bias and variance as the approach of discrete prolate spheroidal sequence multitaper spectral analysis.
