A new approach for joint clock and carrier phase synchronization in digital receivers using a data-aided block based feed-forward architecture is proposed. This approach is based on polynomial approximation of the log-likelihood function by using the Farrow ( 1988) structure. Thus, the maximum likelihood function is expressed in terms of the polynomial-based interpolator filter branches. Simulation results for different types of linear modulations using the conventional Lagrange interpolator and a new optimized interpolator are provided and compared with the theoretical case
