Abstract :
We analyze the joint effects of power control (PC) and slow frequency hopping (SFH). We propose a semi-analytical procedure to determine the outage of SFH TDMA-based mobile radio systems with signal-level-based power control, both for the up-link and the down-link. In the up-link case the procedure is completely analytical whereas the down-link requires a semi-analytical approach to take users´ positions into account. With the aim of showing that the behavior of the systems can be improved by means of suitable choice of the PC parameters, we evaluate the performance of SFH TDMA mobile radio systems in terms of service coverage
