Generalized polynomial exponential sums and their fourth power mean

open access: yesElectronic Research Archive, 2023
<abstract><p>The study of the power mean of the generalized polynomial exponential sums plays a very important role in analytic number theory, and many classical number theory problems are closely related to it. In this article, we use the elementary methods and the properties of the exponential sums to study the calculating problem of one ...

Affine Projection Algorithm Based on Least Mean Fourth Algorithm for System Identification

open access: yesIEEE 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]

open access: yesActa 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 \(\varepsilon\).
