Table 2 Percentage NMSEs in recovery of a half-band cubic phase component from a noisy input signal: Average NMSE values in percentage achieved by the proposed TCR, interpolated half-band Weyl and full-band suboptimal TF projection filters in recovery of the cubic phase component given by Equation (43), listed versus input SNR values
