Abstract :
In this paper, a novel scheme for reducing the envelope fluctuations in OFDM (Orthogonal Frequency division Multiplexing) based on ANFIS (Adaptive Neural Fuzzy Inference Systems) is evaluated when some data can not be modified such as pilot sub-carriers. The loss on the envelope fluctuation reduction is shown to be smaller than 0.3 dB when the proportion of pilots lies into the common values in standards.
