Energy-Efficient Power Adaptation over a Frequency-Selective Fading Channel with Delay and Power Constraints

This paper presents an energy-efficient power allocation for a multicarrier link over a frequency-selective fading channel with a delay-outage probability constraint. The power adaptation maximizes the system energy efficiency (EE), formulated as the ratio of the achieved effective capacity (EC) to...
