Low‐Complexity BFGS‐Based Soft‐Output MMSE Detector for Massive MIMO Uplink

IET Signal Processing, Volume 2023, Issue 1, 2023., 2023
For the massive multiple‐input multiple‐output (MIMO) uplink, the linear minimum mean square error (MMSE) detector is near‐optimal but involves undesirable matrix inversion. In this paper, we propose a low‐complexity soft‐output detector based on the simplified Broyden–Fletcher–Goldfarb–Shanno method to realize the matrix‐inversion‐free MMSE detection ...

Co‐planning of generation and transmission expansion planning for network resiliency improvement against extreme weather conditions and uncertainty of resiliency sources

IET Generation, Transmission &Distribution, Volume 16, Issue 23, Page 4830-4845, December 2022., 2022
Abstract Generation and transmission expansion increase the flexibility of power systems and hence their ability to deal with contingency. This paper presents a resilient‐constrained generation and transmission expansion planning (RCGTEP) model considering the occurrence of earthquakes and floods.

A fast robust numerical continuation solver to a two‐dimensional spectral estimation problem

IET Control Theory &Applications, Volume 16, Issue 9, Page 902-915, 11 June 2022., 2022
Abstract This paper presents a fast algorithm to solve a spectral estimation problem for two‐dimensional random fields. The latter is formulated as a convex optimization problem with the Itakura‐Saito pseudodistance as the objective function subject to the constraints of moment equations.

A Methodology for Obtaining the Different Convergence Orders of Numerical Method under Weaker Conditions

Mathematics, 2022
A process for solving an algebraic equation was presented by Newton in 1669 and later by Raphson in 1690. This technique is called Newton’s method or Newton–Raphson method and is even today a popular technique for solving nonlinear equations in abstract ...

Extended Newton‐type Method for Nonsmooth Generalized Equation under (n, α)‐point‐based Approximation

International Journal of Mathematics and Mathematical Sciences, Volume 2022, Issue 1, 2022., 2022
Let X and Y be Banach spaces and Ω⊆X. Let f:Ω⟶Y be a single valued function which is nonsmooth. Suppose that F:X⇉2Y is a set‐valued mapping which has closed graph. In the present paper, we study the extended Newton‐type method for solving the nonsmooth generalized equation 0 ∈ f(x) + F(x) and analyze its semilocal and local convergence under the ...
