Abstract
This paper proposes a novel adaptive power control scheme to be used in
nonergodic fading channels. We use the decision-theoretic criterion known as
Telser's safety-first criterion and variational calculus to construct the
adaptive power control scheme that maximizes the average transmission rate
subject to the average transmission power constraint and outage probability
constraint for a given target transmission rate. We recognize that for a given
power budget only some combinations of outage probability and target
transmission rate are feasible and derive the boundary of the feasible set of
those parameters. Numerical results suggest that some feasible combinations of
the constraints are inferior to the other ones. We present a practical way to
properly select the superior set of constraints. The proposed scheme is the
extension of the traditional scheme which aims only at minimizing the outage
probability for a given target transmission rate and average transmission
power.
