Abstract
The goal of this thesis was to investigate the filling of a radio cellular system implemented by using narrowband multi-user receivers and transmitter power control.
Transmitter power control has proven to be an efficient method to control interference and to improve spectrum utilization in cellular and personal communication systems. Here we evaluated its potential in combination with multi-user receivers, which in principle shows the possibilities in principle for in-cell channel reuse by assigning multiple signals to the same channel within a cell.
Previous results have shown that a significantly higher capacity can be reached applying these techniques by removing users from a fully loaded system. Our research focused on the filling of the system, developing an admission policy and evaluating its performances.
Results show promising capacity enhancements.
