The mission of the Communications Signal Processing (CSP) Research Group (RG) operating within Centre for Wireless Communications (CWC) and Department of Communications Engineering (DCE) of Faculty of Information Technology and Electrical Engineering is to conduct world-class research, train world-class graduates, create new technology and IPRs, and support society by transferring technology to...

The convergence of columns in the univariate qd-algorithm to reciprocals of polar singularities of meromorphic functions has often proved to be very useful. Any q-column corresponding to a “simple pole of isolated modulus” converges to the reciprocal of the corresponding pole. By performing an equivalence transformation of the underlying corresponding continued fraction and programming the new ...

We give new algorithms for the computation of square roots and reciprocals of power series in CJxK. If M(n) denotes the cost of multiplying polynomials of degree n, the square root to order n costs (1.333 . . .+o(1))M(n) and the reciprocal costs (1.444 . . .+o(1))M(n). These improve on the previous best results, respectively (1.8333 . . . + o(1))M(n) and (1.5 + o(1))M(n).

In introductory level electromagnetism courses the calculation of electrostatic potential and electric field in an arbitrary point is a very common exercise. One most viewed cases symmetry axis centered ring it has been widely studied off charged origin coordinate. this work, we calculated $z$ non using elliptic integrals as pedagogical example application special functions electromagnetism.

We discuss the seminal article in which Le Bellac and Lévy-Leblond have identified two Galilean limits of electromagnetism [1], and its modern implications. We use their results to point out some confusion in the literature and in the teaching of special relativity and electromagnetism. For instance, it is not widely recognized that there exist two well defined non-relativistic limits, so that ...

The metaheuristics are approximation methods which deal with difficult optimization problems. The Work that we present in this paper has primarily as an objective the adaptation and the implementation of two advanced metaheuristics which are the Memetic Algorithms (MA) and the Electromagnetism Metaheuristic (EM) applied in the production systems of Hybrid Flow Shop (HFS) type for the problem of...

In this paper, we study the limitations imposed by the laws of electromagnetism on achievable MIMO channel capacity in its general form. Our approach is a three-fold one. First, we use the channel correlation argument to demonstrate that the minimum antenna spacing under any scattering conditions is at least half a wavelength. Secondly, using a planewave spectrum expansion of a generic electrom...

Electromagnetism is usually understood as a theory describing how charged particles and eletromagnetic elds interact. In this paper I argue that a double ontology comprising both particles and elds is problematic. Either we should think of electromagnetism as a theory about charged particles directly interacting with each other, or as theory of elds whose local interactions are manifested as...
