Abstract:
A method includes processing an input sequence of samples of an orthogonal frequency division multiplexing signal (OFDM) to reduce a peak to average power ratio (PAPR) of the OFDM signal with given constraints of an error vector magnitude (EVM) parameter and a spectral mask parameter for the OFDM signal during a first processing iteration. The method includes performing at least one other iteration of the first processing iteration on a subsequent time domain sequence generated in the first processing iteration to reduce the PAPR of the OFDM signal below a system target PAPR threshold and below threshold limits for the EVM parameter and the spectral mask parameter.
