Fixed and multiple step power control for MC-DS-CDMA in indoor and outdoor environments

Mirza Hamza, Hieu Trung Huynh, Paul Fortier

Abstract

Power control is essential for code-division multiple-access CDMA cellular systems to overcome the near-far problem since all users share the same bandwidth. In this paper, we solve the power control problem for the multicarrier direct sequence CDMA (MC-DS-CDMA) system. We propose two algorithms based on the measure of the signal to interference ratio (SIR) allowing for the elimination of the effect of distance and slow shadowing in the case of indoor and outdoor environments.
