A time-domain based feedback reduction algorithm for orthogonal frequency division multiplexing (OFDM) transmitter power adaptation is proposed, which can significantly reduce the feedback amount during the power adaptation comparing with the conventional frequency-domain adaptation schemes. It is found that the size of cluster plays an important role on the adaptation performance, especially for the vehicular environment. According to simulation results, Lagrange interpolation is used to give an explicit curve between the Doppler frequency, cluster size and the adaptation performance, which makes a good trade-off between the resulted BER and the amount of feedback.
