Abstract :
A technique called iterative amplitude reconstruction (IAR) is proposed for recovering the clipped orthogonal frequency-division multiplexing (OFDM) signals, where optimum equaliser tap coefficients are obtained under the MMSE criterion. The proposed IAR effectively recovers the contaminated OFDM signals, approaching the nonclipped system at the high SNR range
