Abstract
In various literatures, it has been argued that the power variance (PV) can be used as a sound model of peak-to-average power ratio (PAPR) for decisions aimed at reducing the power of the transmitted orthogonal frequency division multiplexing (OFDM) signals. Hence, it has been argued in the past that the PV is a good measure when it comes to power efficiency of OFDM signals. We argue that this may not be always true and that the PV-based power reduction may give misleading results in efforts aimed at PAPR reduction. We support our argument using simulation results. Furthermore, we show that the PV-based comparison in selected mapping reduction technique gives a degraded PAPR performance compared to the actual PAPR-based comparison.
