Reduction of Amplitude Clipping Level with OFDM/TDM
—The OFDM signals have a problem of high peak-to-average power ratio (PAPR). Hence, a large transmit-power backoff or amplitude clipping is required. The amplitude clipping cause...

A Detection Algorithm for Clipped OFDM Signals Using the IDFT-Matrix
A major drawback of the Orthogonal Frequency Division Multiplex (OFDM) principle is the high dynamic range of the transmit signal. The transmit Power Amplifier (PA) and other ele...
