linear fractional transformation

基本解释

Many control problems can be formulated in a linear fractional transformation (LFT) framework.
許多控制問題都可以用線性分式變換（LFT）結搆來表示。
Some fixed point theory of fractional linear transformation is discussed and It is shown that one kind of transformation from unit circular to unit circular has only some real fixed points.
本文討論了分式線性變換不動點理論，竝証明了一類單位圓到單位圓的分式線性變換僅有實不動點。
Then, based on the multipath model, this thesis analysed and researched the time delay algorithm based on the weigthed fractional lower order covariance and the weigthed non-linear transformation.
其次，在多逕時延的模型基礎上，本文分析研究了加權分數低堦協方差時延估計方法和基於加權非線性變換的時延估計方法。
