Abstract

In this paper, continuous heuristic ant colony optimization (ACO_ℝ) [11] procedure is deployed to solve the powerrate optimization problem in multirate multi-processing gain (MPG) DS/CDMA networks. The power-rate allocation design is formulated as a special case of generalized linear fractional problem (GLFP), allowing the multiple access system to operate under best power-rate trade-off operation point. Numerical results considering realistic wireless mobile channels and system operation conditions have been shown the applicability of the ACOR heuristic approach in order to solve this hard problem with practical interest in real energy-efficient, spectral-efficient CDMA systems, as well as of paramount interest in establishing the next wireless generation green communication networks.
