Abstract

Peak cancellation is a widely used technique to reduce peak-to-average power ratio (PAPR) in orthogonal frequency division multiplexing (OFDM) systems. However, peak cancellation, when implemented with a window function in time domain, will introduce in-band distortion and out-of-band radiation due to the nonlinear processing. In this paper, the average power spectral density of cancellation noise is analyzed and estimated by mathematical modeling. Simulation results show that the theoretical derivation can achieve a perfectly coincidence with the simulation result.
