For extensive coverage areas, multi-beam high throughput satellite (HTS) communication is a promising technology that plays crucial role in delivering broadband services to many users with diverse Quality of Service (QoS) requirements. This article focuses on HTS systems where all beams reuse the same spectrum. In particular, we propose novel user scheduling and power allocation design capable ...

A deterministic global optimization algorithm is proposed for locating the global minimum of generalized geometric (signomial) problems (GGP). By utilizing an exponential variable transformation the initial nonconvex problem (GGP) is reduced to a (DC) programming problem where both the constraints and the objective are decomposed into the diierence of two convex functions. A convex relaxation o...

Geometric programming is a mathematical technique, which has been developed for nonlinear optimization problems. This technique is based on the dual program with linear constraints. Determination of species concentrations in chemical equilibrium conditions is one of its applications in chemistry and chemical engineering fields. In this paper, the principles of geometric programming and its comp...
