Abstract

In cellular systems, the objective of transmitter power control is to minimize the average outage probability, which is the probability that the carrier-to-interference ratio for a randomly chosen user is below some threshold. In this paper, we study the impact of power control on the interference diversity properties of error control coding in a frequency hopping system. The results show that algorithms with favourable outage performance in static channel allocation (without interference randomization) does not necessarily improve the system performance in terms of average code-word error probability. It is also found that changing the code parameters does not affect the choice of power control policy
