N2 - In this work, we offer insights on the advantage of using dispersion pre-distortion (DPD) in correlation-based power profile estimation. We also introduce a method to avoid the use of DPD by replacing it with a receiver-side digital correction of the estimated profile. We assess the accuracy of power anomaly estimation and location of the two methods, namely with or without pre-dipsersion at the transmitter side. Our method demonstrates that both approaches exhibit a similar range of applicability by giving at most relative errors of loss estimation around 20% and location around 2% compared to the ground truth.
