In this paper, we present a robust variable step-size decorrelation normalized least-mean-square (RVSSDNLMS) algorithm. A new constrained minimization problem is developed by minimizing the l2 norm of the a decorrelated posteriori error signal with a constraint on the filter coefficients in the l2...

I. INTRODUCTION N adaptive filtering applications for modeling, equalization, control, echo cancellation, and beamforming, the widely used least-mean-square(LMS) algorithm has proven to be both a robust and easily-implementedmethod for on-line estimation of time-varying system parameters. The LMS ...
As a classical augmented complex-valued adaptive algorithm, the augmented complex-valued least mean square (ACLMS) algorithm can obtain the optimal estimate in the sense of minimum mean square error (MMSE) under Gaussian noise assumption and non-circular inputs [11]. In [8], the authors ...
Additionally, there has been little effort to explore whether the pixel-based, PLS-based discriminant algorithm obtained from the PlanetScope dataset can effectively and consistently map the occurrence of different crop diseases. Research progress and practical applications in remote sensing have motivated...
The filter weights updating strategy is called filtered-x least mean square (FxLM S) algorithm asW(n+1)=W(n)+μe(n)[Ŝ(n)*X(n)]where W(n) is defined as W(n)={w(n),w(n-i),…,w(n-K+1)}. X(n) is a vector of reference signal x(n) and it is defined as X(n...
ρλsurface < 0 or ρλsurface > 1, that occurred due to “over correction” by the atmospheric correction algorithm were removed as they are unreliable. The bi-directional reflectance pattern, i.e., lobes of frequently occurring reflectance values (red tones) that occur symmetrically around ...

Prothrombin time (PT) and the associated international normalized ratio (INR) are routinely tested to assess the risk of bleeding or thrombosis and to monitor response to anticoagulant therapy in patients. To measure PT/INR, conventional coagulation test
