1) HLBT
多分辨重叠双正交变换
1.
Unlike the LOT,Hierarchical Lapped Biorthogonal Transform(HLBT)can effectively isolate the energy to a small number of bins in the transform domain by non-uniform division of the signal spectrum.
与LOT相比,多分辨重叠双正交变换(HLBT)对信号频谱的非均匀划分,可以更加有效地将能量集中在有限的变换域子带(TransformBins)上。
2) adaptive hierarchical lapped orthogonal transform (AHLOT)
自适应多分辨重叠正交变换
3) hierarchical lapped transform (HLT)
多分辨重叠变换
1.
AHLOT differs from hierarchical lapped transform (HLT) in that the former produces an arbitrary dyadic nonuniform time axis split, which can be adapted to the signal time-frequency structure, while the latter pays no attention to the signal structure and produces fixed dyadic split.
与时域多分辨重叠变换(HLT)对时域信号的传统二进制非均匀划分不同,AHLOT根据非平稳干扰信号时频结构的时变特性,选择与干扰信号相匹配的最佳基函数,对信号进行自适应二进制非均匀分割。

补充资料：正交变换
设m是对称矩阵， p是可逆矩阵， n=p^tmp 称为 m的正交变换。
正交变换不改变m的特征值。
