On power adaptation in adaptive signaling systems

  title={On power adaptation in adaptive signaling systems},

  journal={IEEE Trans. Communications},
The Shannon capacity of a fading channel under an average-power constraint with channel side information at the transmitter and receiver is only negligibly larger than the capacity of the same channel when constant-power transmission is employed. However, power adaptation has been shown to be quite useful in practical systems, where it has been conjectured that it allows for compensation of the effect of rate quantization. Here, an averagebit-error probability constraint is employed instead of… CONTINUE READING
