英文摘要:
In this paper we present a slight modification of the Fourier estimation method of the spot volatility (matrix) process of a continuous It\\^o semimartingale where the estimators are always non-negative definite. Since the estimators are factorized, computational cost will be saved a lot.

中文摘要:
本文对连续It^o半鞅现货波动(矩阵)过程的Fourier估计方法作了一点改进,其中估计量总是非负定的。由于估计量是因式分解的,因此计算成本将大大降低。
