The relationship among the peak-to-average power ratio (PAPR), aperiodic autocorrelation co-efficient and power variance (PV) is discussed. We show that low values of PV do not always correspond to low values of PAPR as has been mentioned in literature. Hence PV cannot be used as a basis for comparison and measure of PAPR for OFDM signals. Further through simulations we assert that PV can be a good criterion for high values for PAPR, while for the moderate ones it might fail. Finally, we show that PV based comparison in SLM and PTS techniques gives degraded PAPR performance compared to the actual PAPR based comparison.
