Abstract
Power optimization problems are sometimes more convenient to be solved in the signal-to-interference ratio (SIR) domain. However, this methodology requires a characterization of the feasible SIR region. We derive a log-convexity property of the feasible SIR region, which is potentially useful for the design of a power-controlled system.
