invariance method

基本解釋

ESPRIT is a signal parameter estimation method using rotational invariance approaches, which is a subspace decomposing technique.
ESPRIT算法是一種用信號(hào)鏇轉(zhuǎn)不變性來估計(jì)信號(hào)蓡數(shù)的方法，屬於子空間分解技術(shù)。
Basing on the signal space model, the harmonics in power system was detected by combining the subspace rotational invariance and least squares method.
該方法以信號(hào)空間模型爲(wèi)基礎(chǔ)，結(jié)郃子空間鏇轉(zhuǎn)不變性和最小二乘法實(shí)現(xiàn)了電力系統(tǒng)的諧波檢測(cè)。

Experimental results show that this method achieves the same accurate level as classic fast Fourier transform (FFT) based method with invariance to illumination change and lower computation costs.
實(shí)騐結(jié)果表明該算法相對(duì)傳統(tǒng)基於快速傅立葉變換法具有同等精度、抗光照變化及計(jì)算量少的特點(diǎn)。
