MSE performances of the method proposed which employs polynomial curve fitting whose orders are selected adaptively in Senario 2 for different mobile speed values. Note that the performance of the method proposed exhibits a staircase-like behavior over the SNR values that correspond to the order shifts which can also be cross-checked with the points given in Figure 6.
