Analysis of amplitude and phase predistortion and polynomial-based predistortion in OFDM systems


The major drawback of orthogonal frequency division multiplexing (OFDM) systems is the high peak to average power ratio (PAPR), which significantly limits the power efficiency of the operating power amplifier (PA) to avoid nonlinear distortions. Many predistortion techniques have been proposed to perform PA linearization to compensate nonlinear distortions… (More)
