Abstract
Peak-cancellation is a pre-distortion technique for peak-to-average power ratio (PAPR) reduction in orthogonal frequency division multiplexing (OFDM) systems. The distortion introduced to the transmitted signals can be mitigated on the condition that the signal attenuation factor is known at the receiver. In this paper, to alleviate the distortion and disclose the signal feature of peak-cancellation combined OFDM signals, the signal attenuation factor is analyzed and hence evaluated, which is supported by simulation results.
