On the peak-to-average power of OFDM signals based on oversampling.

On the peak-to-average power of OFDM signals based on oversampling.

Orthogonal frequency-division multiplexing (OFDM) introduces large amplitude variations in time, which can result in significant signal distortion in the presence of nonlinear amplifiers. We introduce a new bound for the peak of the continuous envelope of an OFDM signal, based on the maximum of its...
