Abstract :
Energy-efficient link adaptation is studied for transmission on a parallel channel. The total power dissipation model includes circuit power and a power amplifier inefficiency parameter. Earlier results are derived in various ways based on convex minimization problems and concave maximization problems, respectively. It is shown that the fixed-point algorithm proposed earlier by the authors is equivalent to the Dinkelbach method for solving nonlinear fractional programs.
