The fourth power mean value of one kind two-term exponential sums
AIMS Mathematics, 2022 In this paper, based on the analytic method and the properties of Gauss sums, we study the computational problems of the fourth power mean value of one kind two-term exponential sums through the classification and estimation of Dirichlet characters and ...

Affine Projection Algorithm Based on Least Mean Fourth Algorithm for System Identification
IEEE Access, 2020 In the field of signal processing such as system identification, the affine projection algorithm (APA) is extensively implemented. However, running such algorithms in a non-Gaussian scenario may degrade its performance, since the second-order moment ...

The mean fourth power of real character sums [PDF]
Acta Arithmetica, 2002 Summary: Let \(\chi_q\) denotes the real character modulo \(q\) whenever it exists. For \(X\) and \(Y\) large enough, we prove \[ \sum_{|q| \leq X}\biggl| \sum_{n \leq Y} \chi_q(n)\biggr|^4 \ll XY^2 X^\varepsilon \] for any \(\varepsilon>0\) and where the implied constant depends on \(\varepsilon\).

Removal of multiple artifacts from ECG signal using cascaded multistage adaptive noise cancellers
Array, 2022 Although cascaded multistage adaptive noise cancellers have been employed before by researchers for multiple artifact removal from the ElectroCardioGram (ECG) signal, they all used the same adaptive algorithm in all the cascaded multi-stages for ...

On relation between the power mean and the logarithmic mean
, 2010 碩士假設x及y是不同的正數，則 Mp = Mp (x , y) 稱冪平均數， L = L (x , y) 稱對數平均數。 Chang[2]已證明 : 在某些限制下的x和y，當q0，Mp < L 。 我們將證明在某些限制下的x和y，當q 0，L > Mp。If x , y are distinct positive numbers, then Mp= Mp (x , y) is called the power mean of x and y .
