Abstract

In this work, the Verhulst model and the Perron-Frobenius theorem are applied on the power control problem which is a concern in multiple access communication networks due to the multiple access interference. This paper deals with the performance versus complexity tradeoff of both power control algorithm (PCA), as well as highlights the computational cost aspects regarding the implementability of distributed PCA (DPCA) version for both algorithms. As a proof-of-concept the DPCA implementation is carried out deploying a commercial point-floating DSP platform. Numerical results in terms of DSP cycles and computational time as well indicate a) feasibility of implementing the PCA-Verhulst model in 2G and 3G cellular systems; b) high computational cost for the PCA-Perron-Frobenius model.
