Summary:In this article we deal with total transmit power minimization problem in SC-FDMA system constrained to Quality of Service (QoS) and user satisfaction constraints. Through algebraic manipulations we were able to convert an integer nonlinear optimization problem in an Integer Linear Problem (ILP) so as to obtain the optimal solution. Motivated by the high computational to obtain the optimal solution, we propose a low computational complexity suboptimal solution. The results obtained through computational simulations show that the proposed solution presents satisfactory results regarding both outage rate and energy consumption.
